Eval() Does Not Assign Variable At Runtime

I use eval() to assign a list to a var: eval('mylist = [1,2,3]') but when I run it , I got a SyntaxError. What's wrong with it? If I cannot do assignment in the eval(), how do I

Solution 1:

Use exec for statements:

>>>exec'lis = [1,2,3]'>>>lis
[1, 2, 3]

eval works only on expressions, like 2*2,4+5 etc

eval and exec are okay if the string is coming from a known source, but don't use them if the string is coming from an unknown source(user input).
