eval SyntaxError: invalid syntax in python

by

For dynamic execution of statements use the exec function:

>>> exec('y = 3')
>>> y
3

eval usage: eval(expression).

The expression argument is parsed and evaluated as a Python expression.

e.g.:

>>> s = 3
>>> eval('s == 3')
True
>>> eval('s + 1')
4
>>> eval('s')
3
>>> eval('str(s) + "test"')
'3test'
