Use string upper() method to convert every element in a list of strings into uppercase (capitalize) in Python code.
Example capitalize elements in list Python
Simple python example code.
Using an upper() method with Loop
Use a Python for loop to iterate through each item in a given list of strings by index. Then use the string upper() method on each string and reassign it to the corresponding index in the list for that string.
list1 = ["a", "b", "c"] for i in range(len(list1)): list1[i] = list1[i].upper() print(list1)
Use a list comprehension
[x.upper() for x in ["a","b","c"]]
list1 = ["a", "b", "c"] list1 = [each_string.upper() for each_string in list1] print(list1)
Using a map with lambda
list1 = map(lambda x: x.upper(), ["a", "b", "c"]) print(list(list1))
Do comment if you have any doubts and suggestions on this Python list code.
