Сalculating 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.
len(string)
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.
12345string = "Practice is the key to success" length = len(string) print("Here is the string:", string) print("And its length is", length)
The len() function counts every character in the string, including spaces. In the example, "Practice is the key to success" has 30 characters, so len(text) returns 30.

Time to practice:
- Get the last character of the variable
stringusing negative indexation and assign the result to the variablesymbol1. - Extract the index of the last character of the variable
stringusing thelen()method and assign the result to the variablesymbol2.
Note that len(word) equals the length of the word, but len(word)-1 equals the index of the last character of the word.

Can you explain how to count only the letters, excluding spaces and punctuation?
What happens if the string is empty?
Can I use `len()` with other data types besides strings?
Чудово!
