Question

我正在学习Python并且需要修复我的代码以在Python 3.6中产生预期的结果，我在Windows 10上，需要删除尾随的逗号

我的代码：

food_tuple = ("Cheese", "Olives", "Bread", "Salmon", "Juice")

print ("Old Menu: ")

space = ","

for food in food_tuple:
    print (food, end=space)

food_tuple = ("Cake", "Turkey", "Oats", "Salad", "Juice")

print()
print("New Menu: ")

for food in food_tuple:
    print (food, end=space)

当前输出：

Old Menu: 
Cheese,Olives,Bread,Salmon,Juice,  
New Menu: 
Cake,Turkey,Oats,Salad,Juice,

预期产出：

Old Menu: 
Cheese,Olives,Bread,Salmon,Juice

New Menu: 
Cake,Turkey,Oats,Salad,Juice

Answer 1

你可以用两种方式做到这一点

food_tuple = ("Cheese", "Olives", "Bread", "Salmon", "Juice")

print ("Old Menu: ")

space = ","

for food in food_tuple: 
    print (food, end=space)

food_tuple = ("Cake", "Turkey", "Oats", "Salad", "Juice")
print()
print("New Menu: ")

for food in food_tuple[:-1]:
    print (food, end=space)
print(food_tuple[-1])

或

food_tuple = ("Cheese", "Olives", "Bread", "Salmon", "Juice")

print ("Old Menu: ")

space = ","

for food in food_tuple: 
    print (food, end=space)

food_tuple = ("Cake", "Turkey", "Oats", "Salad", "Juice")
print()
print("New Menu: ")


print (','.join(food_tuple))

两种方法都提供了所需的输出
