[FIXED] f-string e Logical Operators OR?

Issue

I have a very simple problem that I never thought I'd encounter with the or operator and an f-string. The problem is that one of the phrase_1_random random variables is always printed. While phrase_2_random is NEVER printed. What am I doing wrong?

I DON'T HAVE TO PRINT THEM BOTH AT THE SAME TIME

I would like to print phrase_1_random or phrase_2_random, but X, Y or Z are never printed

import random

text_1 = ("A", "B", "C")
text_2 = ("X", "Y", "Z")

phrase_1_random = random.choice(text_1)
phrase_2_random = random.choice(text_2)

result= f"{phrase_1_random}" or "{phrase_2_random}"
#or f"{phrase_1_random}" or f"{phrase_2_random}"
print(result)

Solution

It sounds like you're hoping that the or operator will perform some sort of random selection of phrase_1_random or phrase_2_random, but that isn't what the or operator does.

What the or operator does

When the or operator is used in the syntax you've provided above, it will evaluate the values to the right of the assignment operator (=) from left to right. The first value that is "truthy" (in this case, the first value that is a non-empty string) will be used for assignment.

Example:

a = ""
b = "B"
thing = a or b   # thing will be "B"

x = "X"
y = "Y"
thing2 = x or y    # thing2 will be "X"

What you probably want

If you'd like some sort of random selection from either phrase_1_random or phrase_2_random, you could use the random library for that as well:

result= random.choice([phrase_1_random, phrase_2_random])
