Python loop to call different variables

Question

I am trying to create loop in Python to call different variables.

example0="result1"
example1="result2"
example2="result3"
example3="result4"
example4="result5"


for i in range(5):
    print(example+(i))

The result I expect will be

result1
result2
result3
result4
result5

I have tried several solutions, the furthest I got is with :

for i in range(5):
    locals()["example"+str(i)]()

but I recieve error

"    locals()["example"+str(i)]()
TypeError: 'str' object is not callable

Also you can check [this](https://stackoverflow.com/a/55949845/10824407) and [this](https://stackoverflow.com/a/55933230/10824407) answers where I've already explain how you can do this and why you should avoid this. — Olvin Roght, May 24 '19 at 11:59
Unless you have a very specific usage case where you need to access `locals()` directly and cannot create a list or a dictionary instead, it would be advisable to use a list or a dict. It does not seem like you have such a usage case. This is what containers are for. — user10186512, May 24 '19 at 12:02

I guess this would be a way to go:

example0="result1"
example1="result2"
example2="result3"
example3="result4"
example4="result5"


for i in range(5):
    print(locals()["example"+str(i)])

Output:

result1
result2
result3
result4
result5

With the last parentheses you are considering that the variable called result followed by the number you touch is a function. And he must call her. Remove those parentheses. For example:

for i in range(5):
  print locals()["example"+str(i)]

Thank you for the aswer, however I recieved syntax error: print locals()["example"+str(i) ^ SyntaxError: invalid syntax – Matus Hmelar May 24 '19 at 11:59
Are you inside a function, aren't? If you don't have called a function you have to replace locals for globals – Enol García González May 24 '19 at 12:05
I found the reason for that, when I copied your solution, print statement was not inside "for" loop – Matus Hmelar May 24 '19 at 12:21
