在计算单词之间的空格时遇到困难。现在我用下划线代替

我的代码假设是从文件中提取一个短语。我目前正在使用它,但我似乎不知道如何更改输出。在我的输出中,我用下划线表示单词之间的空格。我希望输出具有实际的空格,而不是下划线。在我的代码中,我将每个字符替换为下划线。我认为这是我的问题,因为它也是将空格作为字符来读取的。我的目标是在得到一些帮助的情况下,找出我无法阻止这种情况发生的方法。

更新:问题已修复。现在每个短语的末尾都有一个下划线。有什么建议吗?

    #Define a filename
filename = "puzzles.txt".lower()

#Imports
import random

#Open the file and read
with open(filename) as f:
    lines = f.readlines()
    randomSecretPhrase = (random.choice(lines)) #Choose random phrase from file
    #***Output secret word to screen test***
    print(randomSecretPhrase)

#Initalize        
correct = []
incorrect = []
guesses = []
count = 0

def game():
    for i in randomSecretPhrase:
        if i in correct:
            print(i,end=' ')
        elif i != ' ':
            print('_',end=' ')
        else:
            print(' ',end=' ')
    print("\n\n")
    print('Number of times guessed: ', count)
    print('~~~~~~~~~~~~~~~~~~~~~~~~~~~~')

def guessed_letters():
#Will check the user input to verify valid letter is entered
    while True:
        guess = input("Guess a letter: ").lower()
        if guess in correct or guess in incorrect:
            print("You have already guessed that letter. Please guess again.")
            print(count)
        elif guess.isnumeric():
            print("Please enter only letters not numbers! Guess again.")
        elif len(guess) > 1:
            print("Please enter only one letter at a time. Please guess again.")
        elif len(guess) == 0:
            print("Please enter a letter.")
        else:
            break

#Keep track of correct and incorrect guesses

    if guess in randomSecretPhrase:
        correct.append(guess)
        print('~~~~~~~~~~~~~~~~~~~~~~~~')
        print("You have guessed correctly!")
        print('\n')
    else:
        print('~~~~~~~~~~~~~~~~~~~~~~~~')
        incorrect.append(guess)
        print("You have guessed incorrectly!")
        print('\n')

#Main program
while True:
    #Call game()
    game()
    #Call guessed_letters()
    guessed_letters()
    #Count how many times guesses
    count += 1






Output:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Guess a letter: h
~~~~~~~~~~~~~~~~~~~~~~~~
You have guessed correctly!


b a c k   i n   a   f l a s h _ 


Number of times guessed:  10
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
