How to find the length of a string in Python

How to find the length of a string in Python.

Here's a step-by-step tutorial on how to find the length of a string in Python.

Step 1: Open your preferred Python Integrated Development Environment (IDE) or a text editor.

Step 2: Create a new Python file or open an existing one.

Step 3: To find the length of a string, you can use the built-in len() function in Python. This function returns the number of characters in a string.

Step 4: Declare a string variable and assign a value to it. For example, you can use the following line of code:

my_string = "Hello, World!"

Step 5: To find the length of the string, use the len() function and pass your string variable as the argument. For example:

string_length = len(my_string)

Step 6: Print the length of the string using the print() function. For example:

print("The length of the string is:", string_length)

Step 7: Save your file with a .py extension, for example, string_length.py.

Step 8: Run your Python program. You should see the output displaying the length of the string.

That's it! You have successfully found the length of a string in Python.

Here's a complete example:

my_string = "Hello, World!"
string_length = len(my_string)
print("The length of the string is:", string_length)

Output:

The length of the string is: 13

You can also find the length of a string inputted by the user. Here's an example that asks the user for input and calculates the length:

user_input = input("Enter a string: ")
string_length = len(user_input)
print("The length of the string is:", string_length)

Output:

Enter a string: Python
The length of the string is: 6
