[英]python change global string in function
First off i am very new to coding and python. 首先,我对编码和python非常陌生。 I am trying to call a global string inside of a function.
我正在尝试在函数内部调用全局字符串。 Then I want to change it into an integer.
然后我想将其更改为整数。 Next, I want to apply some Math to the integer.
接下来,我想对整数应用一些数学运算。 Finally I want to convert that integer back to a string and send it back to the global to use in other functions.
最后,我想将该整数转换回字符串,然后将其发送回全局以在其他函数中使用。
I have accomplished most of what I needed to do, but I am having trouble sending the string back to the global. 我已经完成了大部分我需要做的事情,但是我很难将字符串发送回全局。 I have tried using return() but it just quits the program.
我尝试使用return(),但是它只是退出了程序。 Instead I want it to go to another function, while retaining the new value
相反,我希望它转到另一个函数,同时保留新值
Relevant code 相关代码
current_gold = '10'
def town():
global current_gold
print(current_gold)
def pockets():
global current_gold
new_gold = int(current_gold) + 5
new_gold = str(new_gold)
print(new_gold.zfill(3))
input("\tPress Enter to return to town")
town()
This is not the full code. 这不是完整的代码。 I maybe doing stuff drastically wrong though.
我可能做的事情完全错了。
current_gold = '10'
def changeToInt():
global current_gold
current_gold = int(current_gold)
print(type(current_gold)) # It's a string right now
changeToInt() # Call our function
print(type(current_gold)) # It's an integer now
Or you could do it by passing a parameter to your function like so: 或者,您可以通过将参数传递给函数来实现,如下所示:
current_gold = '10'
def changeToInt2(aVariable):
return int(aVariable)
print(type(current_gold)) # It's a string right now
current_gold = changeToInt2(current_gold) # make current_gold the output of our function when called with current_gold as aVariable
print(type(current_gold)) # It's an int now
