9. Strings - Other Functions#

9.1. Duplication#

We can make multiple copies of a string with * followed by an integer.

1print("test" * 5)
2a = 2
3s = "test"
4print(s * a)

testtesttesttesttest
testtest

9.2. Changing Case#

Python also has several string methods to change the case of a string.

1line = "a tale of two cities"

Capitalize the first word:

1line.capitalize()

'A tale of two cities'

Capitalize all of the words:

1line.title()

'A Tale Of Two Cities'

Convert all characters to uppercase:

1line.upper()

'A TALE OF TWO CITIES'

Convert all characters to lower case:

1'A Tale Of Two Cities'.lower()

'a tale of two cities'

9.3. Aligning Strings#

Python also offers a way to align a string within a given number of characters (by default, a space). You can specify a fill character in the optional second argument.

1line = 'A tale of two cities'
2line.center(50)   # center the string within 50 spaces

'               A tale of two cities               '

1line.center(50,'-')

'---------------A tale of two cities---------------'

1line.ljust(50)    # left justify the string within 50 spaces

'A tale of two cities                              '

1line.rjust(50)    # right justify the string within 50 spaces

'                              A tale of two cities'

9.4. Exercises#

  1. Capitalize each word in the following string:
    book_title = 'the hitchhiker\'s guide to the galaxy'
