SwapCase Type - I (PCTS)

 SwapCase Tutorial 

Swapcase is a program to change the cases of the texts (strings), i.e. changing the capital font to small and vice versa. This program can be used to improve the basic python knowledge of python strings and can show how the swapcase() function works internally. It can be done using a lot of algorithms. I'll show you guys 2 tutorials to do the same. In this article, I'll only show the 1st method, then 2nd method will be shown in the next article which would be posted next day.

> Method-I

Copy the following code:

#swapcase (method 1)
s = input("Enter your string:")
s2 = ""
l = len(s)
for i in range(l):
    if s[i].isupper()==True:
        s2 += s[i].lower()
    elif s[i].islower()==True:
        s2 += s[i].upper()
    else:
        s2 += s[i]
print("Your string after swapping cases:",s2)
