This is the code I have written:
import sys
import string
def reverse(li):
li=li[::-1]
return li
a=raw_input("Enter first line ")
c=[]
c=a[0:2]
a=reverse(a)
b=[]
i=0
for i in range(0, len(a)):
if(a[i]==' '):
b=a[:i]
b=reverse(b)
b.append(c)
print b
Here the error is: 'str' object has no attribute 'append' on line b.append(c).
Why is this error creeping up? Where am I going wrong?
It's because you make b a string with this line:
b=str(reverse(b))
Doing so overshadows the list. Pick a different variable name to solve your problem.
Also, there is no need to make a function reverse because Python has a built-in reversed function:
>>> a = [1, 2, 3]
>>> reversed(a)
<listreverseiterator object at 0x015AC6B0>
>>> list(reversed(a))
[3, 2, 1]
>>>
You are turning b into a string in the line above it:
b=str(reverse(b))
Hence, b is now a string and it won't support the .append() method which is for lists.
In python str object does not have an append() method but list object has append() method
In your code
b = []
Initially you defined b as a list
b=reverse(b)
But this statement in your code will convert b from list to str
As str object i.e b does not have an append() you will get an error
