Python Two Given Strings and Swap First Two Characters of Each String

To swap first two characters of given string in python; In this python post, we would like to share with you various python programs:- To swap first two characters of given two strings in Python.

Algorithm to Swap First Two Character of Given Two String

• First of all, the program has 2 strings attached to the user and will store them in a variable.
• After this, we will swap the first two variables of the given strings using the Python slicking method and replus () method. Also keep them in new variables.
• In the last, we will print those new variables. In which we put the swap strings.

Program 1:

• Allow user to input strings one by one, which user want to swap first two characters.
• Swap string using slicing , replace() method and store result in variables.
• Print results.

#take strings from user
str1 = input("Please Enter First String : ")
str2 =input("Please Enter Second String : ")

x=str1[0:2]

str1=str1.replace(str1[0:2],str2[0:2])

str2=str2.replace(str2[0:2],x)

print("Your first string has become :- ",str1)
print("Your second string has become :- ",str2)

After executing the program, the output will be:

Please Enter First String :  sam
Please Enter Second String :  mak

Your first has become :-  mam
Your second has become :-  sak

Program 2:

• Allow user to input strings one by one, which user want to swap first two characters.
• Swap string using slicing and store result in variables.
• Print results.

#take input string from user
str1 = input("Please Enter First String : ")
str2 =input("Please Enter Second String : ")

#swap first two characters of given string
x = str2[:2] + str1[2:]
y = str1[:2] + str2[2:]

#print result
print("Your first has become :- ",x)
print("Your second has become :- ",y)

After executing the program, the output will be:

Please Enter First String :  sam
Please Enter Second String :  mack
Your first has become :-  mam
Your second has become :-  sack
