Python | Convert case of elements in a list of strings
Given a list of strings, write a Python program to convert all string from lowercase/uppercase to uppercase/lowercase.
Input : ['GeEk', 'FOR', 'gEEKS'] Output: ['geeks', 'for', 'geeks'] Input : ['fun', 'Foo', 'BaR'] Output: ['FUN', 'FOO', 'BAR']
Method #1 : Convert Uppercase to Lowercase using map function
# Python code to convert all string # from uppercase to lowercase. # Using map function out = map(lambda x:x.lower(), ['GeEk', 'FOR', 'gEEKS']) # Converting it into list output = list(out) # printing output print(output) |
Output:
['geek', 'for', 'geeks']
Method #2: Convert Lowercase to Uppercase using List comprehension
# Python code to convert all string # from uppercase to lowercase. # Initialisation input = ['fun', 'Foo', 'BaR'] # Converting lst = [x.upper() for x in input] # printing output print(lst) |
Output:
['FUN', 'FOO', 'BAR']
