Python3, Random entries into a format string problem-CodePudding

I am making a program that generates the phrase, "The enemy of my friend is my enemy!" actually, I want this phrase to print out a random permutation of (Friend/Enemy) in each place every time it is re-ran.

so far I got the code to print out the same word 3 times in each, but not a different word in each place.

I couldn't get python to access each string individually from a list. Any ideas?

Thanks!

import random

en = 'Enemy'
fr = 'Friend'
words = en, fr

for word in words:
    sentence = f"The {word} of my {word} is my {word}!"
    print(sentence)

CodePudding user response：

If you want to print random sentence each time a script is run, you can use random.choices to choose 3 words randomly and str.format to format the new string. For example:

import random

en = "Enemy"
fr = "Friend"
words = en, fr

sentence = "The {} of my {} is my {}!".format(*random.choices(words, k=3))
print(sentence)

Prints (randomly):

The Enemy of my Friend is my Friend!

CodePudding user response：

I'd make more changes to the code as it looks like the code in the question is trying to use the wrong tools.

import random

words = ['Enemy', 'Friend']

# three independent draws from your words
w1 = random.choice(words)
w2 = random.choice(words)
w3 = random.choice(words)

# assemble together using an f-string
sentence = f"The {w1} of my {w2} is my {w3}!"
print(sentence)

Not sure if this will be easier to understand, but hopefully!
