The most Pythonic way is to use the len(). Keep in mind that the ‘\’ character in escape sequences is not counted and can be dangerous if not used correctly. Do you want to find the length of the string in python language? If you want to find the length of the word, you can use the len function.

How do you find the length of a string in Python?
Using the len() method – To calculate the length of a string in Python, you can use the built-in len() method. It takes a string as a parameter and returns an integer as the length of that string. For example, len(“educative”) will return 9 because there are 9 characters in “educative”.
What function calculates the length of a string in Python stack overflow?
To get the length of a string, use the len() function.
Is size () used to find string length?
C++ Program to Find the Length of a String You can get the length of a string object by using a size() function or a length() function. The size() and length() functions are just synonyms and they both do exactly same thing.
What is string length ()?
Java – String length() Method This method returns the length of this string. The length is equal to the number of 16-bit Unicode characters in the string.
Is string length or size?
String size() in C++ – String size in the C++ function is the string class’s public member function and finds the string’s size in constant time. Also, the size() function can be used to find the size of the STL containers such as vector, map, set, etc.
As in normal language, we talk about the size of containers, and for the words, sentences, and paragraphs, we usually talk about length. So just for this case, another function, length(), is defined in C++. Both string size() in C++ and string length() in C++ is the same and give the same result. We can say both are synonyms.
Warning: String size() in C++ return value has the data type of long unsigned int (integral) that is also represented as size_t, and if we are using C++ 11 or older version of C++, then at the point of comparing with integer variable compiler will give warning about it.
- For example: Warning: Output: The above code is working fine and printed the correct output, but with the output, we also get a warning about a different type of data type for comparison.
- This warning by the compiler is only generated because we have different data types of variables we are comparing for loop termination condition, which will occur for C++ version C++11 or older.
For C++14 or new versions, it will work fine, and the compiler will give no warning. To remove the warning, we can explicitly convert the data type of return value to an integer, which makes both variables of comparison of the same data type, and it will work fine.

We sometimes come through situations where we require to get all the word lengths present in the string, this can be a tedious task done using a naive method. Hence having shorthand to perform this task is always useful. Let’s discuss certain ways to achieve this.

Output : The original string is : Geeksforgeeks is best Computer Science Portal The list of words lengths is : Time complexity: O(n) Auxiliary Space: O(n), where n is length of string. Method #2: Using regex( findall() + len() In the cases which contain all the special characters and punctuation marks, as discussed above, the conventional method of finding words in a string using split can fail and hence requires regular expressions to perform this task.
import re test_string = “Geeksforgeeks, is best @# Computer Science Portal.!!!”

Output : The original string is : Geeksforgeeks is best Computer Science Portal The list of words lengths is : Time complexity: O(n), where n is the length of the test_list. The regex( findall() ) + len() takes O(n) timeAuxiliary Space: O(n), extra space of size n is required Method #3: Using numpy Note: Install numpy module using command “pip install numpy”
res = np.char.str_len(test_string.split()) print ( “The list of words lengths is : ” + str (res.tolist())) |
Output : The original string is : Geeksforgeeks is best Computer Science Portal The list of words lengths is : Another way to find the word length in a string is to use numpy. The numpy library has a function numpy.char.str_len() which can be used to find the length of each word in the string.
Time complexity: O(n) Auxiliary Space: O(n) Method #4: Using map() In this approach, we first split the string into individual words using the split() method, which returns a list of words. We then use a generator expression to iterate over the words in the list and get their lengths using the len() function.
The resulting generator object is passed as the second argument to the map() function, which applies the len() function to each element of the generator and returns an iterator of the resulting lengths. Finally, we convert the iterator to a list using the list() function and return the resulting list of lengths.
- In the example usage, we call the function with a sample string s.
- The output will be a list of integers representing the lengths of all the words in the string.
- In this case, the output will be, which corresponds to the lengths of the words “This”, “is”, “a”, “sample”, and “string”, respectively.
- This approach using a generator expression and the map() function may be more memory-efficient than the previous approaches using list comprehensions, as it avoids creating a new list to store the lengths of the words.
Instead, it produces the lengths as an iterator, which can be converted to a list if needed.

Output The original string is : Geeksforgeeks is best Computer Science Portal The list of words lengths is : Time complexity: O(n), where n is the length of the input string since we iterate over the string once.Auxiliary space: O(m), where m is the number of words in the input string since we store the length of each word in a list. : Python | Words lengths in String – GeeksforGeeks
How to check string length in Python pandas?
Len() method is used to determine length of each string in a Pandas series. This method is only for series of strings. Since this is a string method,. str has to be prefixed everytime before calling this method.
Can you find the length of a stack Python?
Functions associated with Python Stack – There are a bunch of useful functions in Python that help us deal with a stack efficiently. Let’s take a brief look at these functions –
len() – This stack method is used for returning the size of the stack. This function can also be used in the definition of isempty() method in a Python stack. append(n) – This Python function is used for inserting an element into the stack. The element to be pushed is passed in its argument. pop() – This method, associated with the Python lists, is used for deleting the topmost element from the stack.
Can you use Len on strings in Python?
What is len() in Python? How to Use the len() Function to Find the Length of a String
- In programming languages, getting the length of a particular data type is a common practice.
- Python is no different because you can use the built-in len() function to get the length of a string, tuple, list, dictionary, or any other data type.
- In this article, I’m going to show you how to get the length of a string with the len() function.
How to calculate the length of each word in a string in Python?
Str_len() which can be used to find the length of each word in the string.
How do I print Len in Python?
Python len() function Syntax: – len(Object) Parameter:
Object: Object of which we have to find the length for example string, list, etc.
Returns: It returns the integer value which indicates the length of an object. For example, we can find the total number of characters in a string using the Python len() Function. It can be used with different types of except some of them. Example: Input: “geeksforgeeks” Output: 13 Explanation: The input string contains 13 characters so output is 13.
How do I find the length of a string in Pandas?
Step 1: Define a Pandas series of string. Step 2: Find the length of each string using the str. len() function. Step 3: Print the results.
