Here are 2 ways to convert all elements in a list to upper case:
(1) Using a List Comprehension:
my_list = ['aa', 'bb', 'cc', 'dd', 'ee'] upper_case_list = [i.upper() for i in my_list] print(upper_case_list)
The result:
['AA', 'BB', 'CC', 'DD', 'EE']
(2) Using a For Loop:
my_list = ['aa', 'bb', 'cc', 'dd', 'ee'] upper_case_list = [] for i in my_list: upper_case_list.append(i.upper()) print(upper_case_list)
The result:
['AA', 'BB', 'CC', 'DD', 'EE']
Alternatively, you may use the following generator to convert all the elements in your list to upper case:
Enter List Name:
Enter List Values:
Enter New List Name:
