无法为函数调用或不支持操作数类型为 - =：'str'和'int'

Question

要从变量“glory”中取1，变量需要是整数。当它变成一个整数时，我只会收到：“无法分配函数调用”。

import sys 

glory = input("Glory charge: ") 
glory_prev = glory 
print(glory_prev) 
pouch = 28 
run_num = 0 
nat_price = input("Nat price: ") 

while True: 
    run = input("You've done " + (str(run_num)) + " runs: ") 
    if run == "a": 
     (int(glory) -= 1 
     pouch -= 1 
     if glory == 0: 
      print("New glory needed") 
      glory = glory_prev 
     if pouch == 0: 
      print("Repair pouch") 
      pouch = 28 

    elif run == "q": 
     sys.exit 
    else: 
     continue 

请帮忙，谢谢。

你必须要考虑的唯一的事情是荣耀INT之前移除支架和更改荣耀语法

glory = int(glory) - 1 

这样的代码会是这样

import sys 

glory = input("Glory charge: ") 
glory_prev = glory 
print(glory_prev) 
pouch = 28 
run_num = 0 
nat_price = input("Nat price: ") 

while True: 
    run = input("You've done " + (str(run_num)) + " runs: ") 
    if run == "a": 
     glory = glory - 1 
     pouch -= 1 
     if glory == 0: 
      print("New glory needed") 
      glory = glory_prev 
     if pouch == 0: 
      print("Repair pouch") 
      pouch = 28 

    elif run == "q": 
     sys.exit 
    else: 
     continue
