我想创建一个带有尝试计数器的随机数生成器，但它说“无法分配给操作员”这是我目前所拥有的

  import random
    number=random.randint(1,10)
    print ("i am thinking of a number between 1 and 10")
    counter=5
    while counter>0:
        if number==int(input("guess what the number is:  ")):
            print("well done")
        else:
            counter-1=counter #it displays it hear before the 1st counter
            print ("your bad try again")
    print ("it was" ,number,)

【问题讨论】：

counter-1=counter - 你认为那会怎样？

【解决方案1】：

可能是因为

counter-1=counter

但您应该发布格式清晰的代码，以便轻松查看错误所在！

【解决方案2】：

你不能修改变量名：

 import random
    number = random.randint(1, 10)
    print("i am thinking of a number between 1 and 10")
    counter = 5
    while counter > 0:
        if number == int(input("guess what the number is:  ")):
            print("well done")
        else:
            counter = counter - 1 # you cant modify a variable name
            print("your bad try again")
    print("it was", number, )

输出：

i am thinking of a number between 1 and 10
guess what the number is:  5
your bad try again
guess what the number is:  4
your bad try again
guess what the number is:  3
your bad try again
guess what the number is:  2
your bad try again
guess what the number is:  1
your bad try again
it was 7

您的代码的问题在于如何减少 counter 变量。

这里是for 循环的更好解决方案。它会为您递减。

import random
number=random.randint(1,10)
print ("I am thinking of a number between 1 and 10")
print ("Guess what the number is - ",end='')
for __ in range(5):
    if number==int(input()):
        print("well done")
        break
    else:
        print ("your bad try again")
print ("Number was " ,number)
