循环嵌套函数并运行多次

Question

我有一个 Python 代码需要帮助。我的目标是让代码循环嵌套函数并根据我添加的文本数量运行多次。对于我的代码，我希望它运行 main_func() 3 次。

期望的输出

#First loop

I am first apple

I am second apple

I am third banana

#second loop

I am first apple 

I am second apple

I am third banana

#third loop

I am first apple

I am second apple

I am third banana

def main_func():
 
    fruits = []  # List

    fruits.append("apple")
    fruits.append("cherry")
    fruits.append("banana")

    for fruit in fruits:
      for i in range(3):  # Iterate 3 times
        print(fruit)
        
    def first():
       print("I am first", (fruit))
    
    first()
    def second():
        print("I am second", (fruit))
        
    second()
    
    def third():
        print("I am third", (fruit))
        
    third()
    
main_func()

Answer 1

您可以创建一个迭代 3 次的方法并调用

first

、

second

、

third

。

您可以在下面找到修改后的代码片段。

def main_func():
 
    fruits = []  # List

    fruits.append("apple")
    fruits.append("cherry")
    fruits.append("banana")

    def first():
       print("I am first", (fruits[0]))
    
    def second():
        print("I am second", (fruits[1]))
        
    
    def third():
        print("I am third", (fruits[2]))
    
    def printFruits():
        for i in range(3):
            first()
            second()
            third()
    printFruits()
main_func()

输出：

I am first apple
I am second cherry
I am third banana
I am first apple
I am second cherry
I am third banana
I am first apple
I am second cherry
I am third banana
