python：带参数的函数和收集输入然后打印返回值

Question

我目前正在EDX中参加初学Python课程，需要有关其所需编码活动的帮助。

计划：

fishstore()
create and test fishstore()

fishstore() takes 2 string arguments: fish & price
fishstore returns a string in sentence form
gather input for fish_entry and price_entry to use in calling fishstore()
print the return value of fishstore()

example of output: Fish Type: Guppy costs $1

Answer 1

def fishstore():
    fish_entry = input("Input fish ")
    price_entry = input("Input price ")  
    return "Fish Type: " +str(fish_entry) + " costs " + str(price_entry)
a = fishstore()
print (a)

这是整个代码......你不明白哪一部分？

Answer 2

def fishstore(fish,price):

    return ("Fish Type: "+ fish.capitalize() + " costs $" + price)

fish_entry=input('Enter fish type: ')
price_entry=input('Enter fish type price: ')
print (fishstore(fish_entry,price_entry))
