str1="This is a Case "
print(str1.swapcase())
print(str1)
I expect the output for both print statements to be swapped as:
"tHIS IS A cASE" but the output for first print is "tHIS IS A cASE" and second print is the original str1.

Probably (don't know python) because swapcase returns a new string and does not change the original variable – Hans Kesting Jan 26 '19 at 14:30

swapcase doesn't change the string that you call it on, it returns a new string. If you want to change the original string, you have to reassign it with the returned value.
str1 = str1.swapcase()

I tried, apparently we need to assign to a new string since they are immutable. So, str2=str1.swapcase(). Thank you! – Lastika Sethi Jan 28 '19 at 12:50
