[FIXED] An error for converting elements in a list

Issue

I am a iPython beginner and I need some help with my code. I want to read 6 values from input. They can be integers, floats, complex numbers, strings or lists. After reading the values and appending them to a list, I do the following conversion:

• for integers: replace it with the square root inside the list.

• for floats: replace it with the cosine of the number inside the list.

• for complex numbers: replace it with its real part inside the list.

• for strings: turn it to capital letters inside the list.

• for lists: discard the last element.

The program throws the following error:

File "<ipython-input-1-1f00b88d82c9>", line 20
    else i is list:
         ^
SyntaxError: invalid syntax

and also it can not store a string value into list. It always stores . how should I solve this error? Here is my code:

import math as m
l=[]
i=0
while i<6:
    x=input("Enter some values: ")
    if isinstance(x,str):
        x=int(x)
    l.append(x)
    i=i+1
print l
for i in l:
    if i is str:
        i=s.capitalize(i)
    elif i is int:
        i=m.sqrt(i)
    elif i is float:
        i=m.cos(i)
    elif i is complex:
        i=l.real(i)
    else i is list:
        n=len(l)
        i=remove[n-1]
print l

Solution

Just replace

else i is list:

with

elif i is list:

Since you need to evaluate a condition even in your last case, you need the 'if' functionality, so use elif. else cannot be followed immediately by a condition, hence the error you saw.
Also, you have error in line

i=remove[n-1]

If you want remove last element from list i you need

del i[-1]
