Python program to convert a list to string Archives

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

out = map(lambda x:x.lower(), ['GeEk', 'FOR', 'gEEKS'])

output = list(out)

print(output)

Output:


['geek', 'for', 'geeks']

Method #2: Convert Lowercase to Uppercase using List comprehension

input = ['fun', 'Foo', 'BaR']

lst = [x.upper() for x in input]

print(lst)

Output:


['FUN', 'FOO', 'BAR']
