 SwapCase Tutorial  S wapcase 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) ©SGPython

 Python Codes The Series -1 ©Photo by wiki commons Not only in Python but also in the day-to-day life, the letters in English alphabets are characterized into two cases viz. upper case and lower case. Our first program will be a general fun program for the beginners. In this program, we will learn to swap the cases of the letters of English alphabets being entered by the user with the help of a few lines of Python code. For example: If the user enters: " hoLa AmIGo" , the python program would convert this string into " HOlA aMigO" . The Program is noted below: string=input("Enter a string :") length=len(string) s='' for i in range(length): if string[i].islower(): s=s+string[i].upper() elif string[i].isupper(): s=s+string[i].lower() else: s=s+string[i] print(s) FOR QUICK REFERENCE: The len() function gives the length of the string and the the input() function takes input from the user.
