Case Changing of Python String Methods
The below Python functions are used to change the case of the strings. Let’s look at some Python string methods with examples:
- lower(): Converts all uppercase characters in a string into lowercase
- upper(): Converts all lowercase characters in a string into uppercase
- title(): Convert string to title case
- swapcase(): Swap the cases of all characters in a string
- capitalize(): Convert the first character of a string to uppercase
Example: Changing the case of Python String Methods
Python3
# Python3 program to show the # working of upper() function text = 'geeKs For geEkS' # upper() function to convert # string to upper case print("\nConverted String:") print(text.upper()) # lower() function to convert # string to lower case print("\nConverted String:") print(text.lower()) # converts the first character to # upper case and rest to lower case print("\nConverted String:") print(text.title()) # swaps the case of all characters in the string # upper case character to lowercase and viceversa print("\nConverted String:") print(text.swapcase()) # convert the first character of a string to uppercase print("\nConverted String:") print(text.capitalize()) # original string never changes print("\nOriginal String") print(text) |
Output
Converted String: GEEKS FOR GEEKS Converted String: geeks for geeks Converted String: Geeks For Geeks Converted String: GEEkS fOR GEeKs Original String geeKs For geEkS
Time complexity: O(n) where n is the length of the string ‘text’
Auxiliary space: O(1)
Python String Methods
Python string methods is a collection of in-built Python functions that operates on lists.
Note: Every string method in Python does not change the original string instead returns a new string with the changed attributes.
Python string is a sequence of Unicode characters that is enclosed in quotation marks. In this article, we will discuss the in-built string functions i.e. the functions provided by Python to operate on strings.
