It is a method in python that swaps the cases of all the alphabets i.e. concerts all the upper case characters to lower case and all the lower case characters to upper case.
s = “CODE, hustle” x = s.swapcase() print(x)
Here “CODE” is converted to “code” (Upper case to lower case) and “hustle” is converted to “HUSTLE” (lower case to upper case).
s = “CODEwindow is a tech PLATFORM” x = s.swapcase() print(x)
codeWINDOW IS A TECH platform
Here all the upper case characters i.e. “CODE” and “PLATFORM” are converted to lower case characters (“code”, “platform”) and all the lower case characters i.e. “window is a tech” are converted to upper case character (“WINDOW IS A TECH”).
