Case conversion in Python

Hello and welcome, in this post we will explore all the methods of Python strings that are used for case conversion in Python. We will see how to use them with one example of each.

1. lower()

Converts every character of the string to lowercase.

my_str = "A STRING"
my_str = my_str.lower()
print(my_str)

Output:

a string

2. upper()

Converts every character of the string to uppercase.

my_str = "a string"
my_str = my_str.upper()
print(my_str)

Output:

A STRING

3. title()

Converts the first character of each word to upper case.

my_str = "a string"
my_str = my_str.title()
print(my_str)

Output:

A String

4. capitalize()

Converts the first character to the upper case.

my_str = "a string"
my_str = my_str.capitalize()
print(my_str)

Output:

A string

5. swapcase()

Swaps cases, the lower case becomes the upper case and vice versa.

my_lower_str = "a string"
my_upper_str = "A STRING"
my_str_1 = my_lower_str.swapcase()
my_str_2 = my_upper_str.swapcase()
print(my_str_1)
print(my_str_2)

Output:

A STRING
a string

6. center()

Returns a centered string.

my_str = "a string"
my_str = my_str.center(20, "-")
print(my_str)

Output:

------a string------

7. casefold()

Converts string into lowercase.

my_str = "a sTRINg"
my_str = my_str.casefold()
print(my_str)

Output:

a string
