How do I execute a string containing Python code in Python?
Editor's note: Never use eval (or exec) on data that could possibly come from outside the program in any form. It is a critical security risk. You allow the author of the data to run arbitrary code on your computer. If you are here because you want to create multiple variables in your Python program following a pattern, you almost certainly have an XY problem. Do not create those variables at all - instead, use a list or dict appropriately.
