为什么我会收到此语法错误？ (Python)

Question

Python 菜鸟在这里。今天下午在 'guess the number game' 荡秋千。对我来说一切都很好，但我在第 26 行不断收到语法错误：

其他player_number>=secret_number:

我什么都试过了，但我根本想不通。感谢您的帮助。

import random, sys
secret_number = random.randint(1, 99)
countdown_timer = 7

print("This is a number guessing game.")
print("You have to guess a number between 1 and 99!")
print("You have 7 attempts to guess the correct number")
print("Good luck!")
print("\n")
print("Your first guess is: ")

while countdown_timer != 0:
    player_number = int(input())
    countdown_timer = (countdown_timer - 1)
    if player_number == secret_number:
        print("\n")
        print("That's it!! The number was: " + secret_number)
        print("\n")
        print("Congratulations!")
        print("Please try again.")
        quit()
    elif player_number <= secret_number:
        print("Higher!")
        print("You have " + int(countdown_timer) + "guesses left.")
        print("Please enter your next guess: ")
    else player_number >= secret_number:
        print("Lower!")
        print("You have " + int(countdown_timer) + "guesses left.")
        print("Please enter your next guess: ")
        
print("You are out of guesses, sorry.")
print("The correct number was: " + secret_number)
print("Please try again.")

Answer 1

将您的 else 语句更改为 elif。 else 语句没有表达式。因此：

elif player_number >= secret_number:
    print("Lower!")
    print("You have " + int(countdown_timer) + "guesses left.")
    print("Please enter your next guess: ")

实际上运行代码之后，我看到您正在尝试连接整数和字符串，但这行不通。要使其工作，请使用 f' 打印。

代码如下：

import random
secret_number = random.randint(1, 99)
countdown_timer = 7

print("This is a number guessing game.")
print("You have to guess a number between 1 and 99!")
print("You have 7 attempts to guess the correct number")
print("Good luck!")
print("\n")
print("Your first guess is: ")

while countdown_timer != 0:
    player_number = int(input())
    countdown_timer = (countdown_timer - 1)
    if player_number == secret_number:
        print("\n")
        print(f"That's it!! The number was: {secret_number}") # f' print here
        print("\n")
        print("Congratulations!")
        print("Please try again.")
        quit()
    elif player_number <= secret_number:
        print("Higher!")
        print(f"You have   {countdown_timer} guesses left.")  # here
        print("Please enter your next guess: ")
    elif player_number >= secret_number:
        print("Lower!")
        print(f"You have   {countdown_timer} guesses left.") #here
        print("Please enter your next guess: ")
        
print("You are out of guesses, sorry.")
print(f"The correct number was: {secret_number}") # and here
print("Please try again.")

Answer 2

我会用“else:”替换整行并添加评论：

    if player_number == secret_number:
        ...
    elif player_number <= secret_number:
        ...
    else:
        # player_number >= secret_number
        ...
