How to convert string to Boolean in Python

Question

I came across this question for the interview. I had to convert the string to Boolean and return the Boolean value

For ex s="3>1>5" => false

I tried using

ans= bool(s)

But I always get the answer as True even though the above example gives False if we don't pass it as a string

If you read the docs for bool() you'll see that it doesn't evaluate the contents of a string passed to it. — jarmod

If you are not allowed to use eval, then you have to do full-scale parsing - unless the expressions in the strings have very simple, regular structure. — DYZ

You must be looking for eval(string)

>>> eval("3>1>5") False
