String Length

Π‘alculating the number of characters in a string is a common operation. It helps in tasks like validation, formatting, or data analysis. Python provides a built-in function len() to get the length of a string.

python

The string parameter refers to the text whose length you want to determine; the len() function returns the total number of characters in that text, including spaces and punctuation marks.


              
12345

            
string = "Practice is the key to success"
length = len(string)

print("Here is the string:", string)
print("And its length is", length)
copy

The len() function counts every character in the string, including spaces. In the example, "Practice is the key to success" has 31 characters, so len(text) returns 31.

Task

Time to practice:

  1. Get the last character of the variable string using negative indexation and assign the result to the variable symbol1.
  2. Extract the index of the last character of the variable string using the len() method and assign the result to the variable symbol2.

Note that len(word) equals the length of the word, but len(word)-1 equals the index of the last character of the word.
