[英]How do you use a loop for a function?
I have written most of the codes already, but I am still having a hard time figuring out the code to loop the program (for a function) as many times the user desires until the user is done.我已经编写了大部分代码,但是我仍然很难找出代码来循环程序(对于函数),直到用户完成为止。 Also, I am unable to use a For loop.
另外,我无法使用 For 循环。
def load():
a=input("Name of the stock: ")
b=int(input("Number of shares Joe bought: "))
c=float(input("Stock purchase price: $"))
d=float(input("Stock selling price: $"))
e=float(input("Broker commission: "))
return a,b,c,d,e
def calc(b,c,d,e):
w=b*c
x=c*(e/100)
y=b*d
z=d*(e/100)
pl=(x+z)-(y-z)
return w,x,y,z,pl
def output(a,w,x,y,z,pl):
print("The Name of the Stock: ",a)
print("The amount of money Joe paid for the stock: $",format(w,'.2f'))
print("The amount of commission Joe paid his broker when he bought the stock: $",format(x,'.2f'))
print("The amount that Jim sold the stock for: $",format(y,'.2f'))
print("The amount of commission Joe paid his broker when he sold the stock: $",format(z,'.2f'))
print("The amount of money made or lost: $",format(pl,'.2f'))
def main():
a,b,c,d,e=load()
w,x,y,z,pl=calc(b,c,d,e)
output(a,w,x,y,z,pl)
main()
Calling a function in a loop is fairly simple, you wrap in either in a while
or a for
loop and call it inside.在循环中调用函数相当简单,您可以将其包装在
while
或for
循环中并在内部调用它。 The below code executes the brookerage
function 10 times.下面的代码执行了 10 次
brookerage
。 I suppose you can use this as an example and customize the entire thing for your needs.我想您可以以此为例,并根据您的需要自定义整个内容。
def brookerage():
a,b,c,d,e=load()
w,x,y,z,pl=calc(b,c,d,e)
output(a,w,x,y,z,pl)
def main():
for i in range(0,10):
brookerage()
main()
To let the user decide if they want to keep looping and not any fixed number of times, ask the user:要让用户决定是否要继续循环而不是任何固定次数,请询问用户:
# in place of the call to main() above, put:
while input('Proceed? ') == 'y':
main()
So it keeps looping over main()
as long as the user enters 'y'.因此,只要用户输入“y”,它就会一直在
main()
循环。 You can change it to 'yes', 'Yes', etc. as needed.您可以根据需要将其更改为“是”、“是”等。
Side note:边注:
1. You should use more than 1 space for indent. 1. 缩进应该使用 1 个以上的空格。 Typically 4 spaces, or at least 2.
通常为 4 个空格,或至少 2 个。
2. read up on if __name__ == "__main__"
. 2.
if __name__ == "__main__"
阅读if __name__ == "__main__"
