In python, type the following into a document.
NOTE: Sentences following a # symbol are comments, and are not necessary for the program to run.
#!/usr/bin/python
#This program takes a input from a user and reverses it.
number = input("Type a number: ") #This takes input from a user.
a = len(number) #This finds the length of the number
reverse = "" #This sets the variable reverse to an empty string.
for i in number:
a = a-1 #The places in a string start from 0. The last value will be the length minus 1.
reverse = reverse + number[a] #Makes the number's last digit the new string's first.
print("The reverse of", number, "is", reverse + ".") #prints the resulting string.
This program will take any sequence of characters and reverse them. The final value is a string, but if an integer is needed, one needs only to add the line
reverse = int(reverse)
above the print statement.
However, this will stop the program from being able to reverse strings, as it is not possible to convert a string to an integer if it is not a number.
