I have to create a program that lets the user enter a string and then, using range, the program outputs that same string backwards. I entered this into python, but it goes me an error, in the 4th line, it says 'int' object has no attribute '__getitem__'.
Can someone please help me correct it? (Using range)
user=raw_input("Please enter a string: ")
user1=len(user)-1
for user in range(user1,-1,-1):
user2=user[user1]
print user2
I think you have a mistake because you keep using the same words to describe very different data types. I would use a more descriptive naming scheme:
user = raw_input("Please enter a string: ")
user_length = len(user)
for string_index in range(user_length - 1, -1, -1):
character = user[string_index]
print(character)
For example, if the user input was foo, it would output:
o
o
f
You are overwriting the user string with your for-loop, fix it by changing the for-loop variable
Fix:
for ind in range(user1,-1,-1):
user2 = user[ind]
print (user2)
Alternative (without for-loop):
print user[::-1]
This is because you are overwriting the string user with an int in the line for user in range(...)
Perhaps you'd be better off with:
user=raw_input("Please enter a string: ")
for user1 in range(len(user)-1,-1,-1):
user2=user[user1]
print user2
your user has been overwrited in your for loop. Take this(Use range)
user=raw_input("Please enter a string: ")
print ''.join([user[i] for i in range(len(user)-1, -1, -1)])
Python 3 solution:
user=input("Please enter a string: ")
for ind in range(1,len(user)+1):
char = user[-ind]
print(char)
And another non for loop solution is:
''.join(reversed(user))
