Write a Python function that will accept as input three string values from a user. The method will return to the user a concatenation of the string values in reverse order. The function is to be called from the main method.

Following are the program in python language

def cat_rev (x, y, z) : # function definition

x=x[::-1]# reverse the first string

y=y[::-1]# reverse the second string

z=z[::-1]# reverse the third string

z=x+y+z; #concat the string

return (z) #return the string

#main method

s=input ("Enter the first string:") #read the first string

r=input ("Enter the second string:") #Read the second string

t=input ("Enter the third string:") #Read the third string by user

rev1 = cat_rev (s, r, t) #function calling

print (rev1) # display reverse string

Output:

Enter the first string:san

Enter the second string:ran

Enter the third string:tan

nasnarnat

Explanation:

Following are the description of program

In the main function we read the three value by the user in the "s", "r" and "t" variable respectively. After that call the function cat_rev () by pass the variable s, r and t variable in that function. Control moves to the function definition of the cat_rev () function. In this function we reverse the string one by one and concat the string by using + operator. Finally in the main function we print the reverse of the concat string.
