In Python,we can define a python function at runtime execute with the help of FunctionType(). First we import types module then perform compile() function and pass parameter exec and after that with the help FunctionType() define the function at runtime.
Example 1: Function to print GEEKSFORGEEKS.
Python3
# importing the module from types import FunctionType # functttion during run-time f_code = compile('def gfg(): return "GEEKSFORGEEKS"', "<string>", "exec") f_func = FunctionType(f_code.co_consts[0], globals(), "gfg") # calling the function print(f_func()) |
Output:
GEEKSFORGEEKS
Example 2: Function to add 2 numbers.
Python3
# importing the module from types import FunctionType # function at run-time f_code = compile('def gfg(a, b): return(a + b) ', "<int>", "exec") f_func = FunctionType(f_code.co_consts[0], globals(), "gfg") val1 = 3999val2 =4999 # calliong the function print(f_func(val1, val2)) |
Output:
8998
