Instead of using strings just use the functions directly:

func_list = (func1, func2, func3)

for f in func_list:
   f()

That avoids the potentially insecure eval and will be faster too.

[Tutor] list of functions

[kay Cee]

Greetings all,

I would like to use a list of functions for an automation project, and this
is the prototype I came up with
###
def func1():
print('func1')

def func2():
print('func2')

def func3():
print('func3')


func_list = ('func1', 'func2', 'func3')

for f in func_list:
eval(f)()
#

The output shows as intended, but I'd like to know if there are any safety
or performance issues using this prototype or if there is a better way to
acheive a list of functions.

Thanks in advance
