Choosing and executing functions in a list of functions

I am trying to write a program that do some random moves, and it have a lot of functions, the program select like a keyword to use the function, but my code get big for something simple, there is a simpler way to write this code?

list_mov = ["R", "RI", "L", "LI", "U", "UI", "D", "DI", "F", "FI", "B", "BI"]

mov = random.choice(list_mov)

# Here i need to make a list of selected functions
resolution.append(mov)

if mov == "R":
    mov_r()
if mov == "RI":
    mov_ri()
if mov == "L":
    mov_l()
if mov == "LI":
    mov_li()
if mov == "U":
    mov_u()
if mov == "UI":
    mov_ui()
if mov == "D":
    mov_d()
if mov == "DI":
    mov_di()
if mov == "F":
    mov_f()
if mov == "FI":
    mov_fi()
if mov == "B":
    mov_b()
if mov == "BI":
    mov_bi()

Everything is an object in python. Functions included. So I can write this:

list_mov = {
  "R": mov_r,
  "RI": mov_ri,
  "L": mov_i,
  ...  # fill in more here
}

mov = random.choice(list(list_mov.keys()))

# Here i need to make a list of selected functions
resolution.append(mov)
# get function, then execute it
func = list_mov[mov]
func()

You can actually select from list of function instances, and then call the one you randomly selected, like:

import numpy as np

def x():
    print("function x!")

def y():
    print("y here.")

def z():
    print("zzz")

av_functions=[x,y,z]
mv=np.random.choice(av_functions)

mv()

In python, everything is an object. You can simply do this: list_mov = [mov_r, mov_l, ...] Because of this, you can use:

mov = random.choice(list_mov)
mov()

You can just create a list of functions and choose from them to a variable (as you do with strings). They all have the same parameters, so it should be easy:

list_mov = [mov_r, mov_ri, ...]
mov = random.choice(list_mov)
resolution.append(mov)
# And finally
mov()
