String Uppercase in Python

Use the upper() method to transform a whole string into uppercase.

regular_text = "This is a regular text."

upper_case_text = regular_text.upper()

print(regular_text)
#This is a regular text.

print(upper_case_text)
#THIS IS A REGULAR TEXT.

Notice that the original regular_text variable remains unchanged, thus you need to assign the return of the method to a new variable, upper_case_text in this case.
