String is a collection of characters. Any character can be accessed by its index. The indexing of a string starts at 0 (or -1 if it’s indexed from the end). We can get the number of characters in a string by using built-in function len. Compared to the indexing, len is not zero based.

# Creating a string
text = 'Some collection of words'

# Assigning the number of characters in the given string to a variable
total_char = len(text)

# Printing the total number of characters
print('Number of characters = {}'.format(total_char))

Number of characters = 24
