# 定义一个函数 def print_variable(variable): print(variable) # 定义一个变量 my_variable = "Hello, World!" # 调用函数并传入变量作为参数 print_variable(my_variable) # 使用循环调用变量 for i in range(5): print(my_variable) 在上述代码中,我们首先定义了一个名为print_variable的函数,该函数接...
pass try: for i in range(10): if i==5: raise BreakLoop except BreakLoop: print("已提前退出循环") ``` 第三步:使用函数封装实现外部退出 我们还可以将循环代码封装到一个函数中,在函数内部通过return来提前退出循环。以下是一个示例: ```python def loop_function(): for i in range(10): if ...
def my_function(): print("Function is called") Using a for loop to call the function 5 times for _ in range(5): my_function() 在这个例子中,我们定义了一个简单的函数my_function,然后使用一个for循环来调用这个函数5次。_是一个常用的占位符变量名,表示我们不关心循环变量的值。 一、使用循环重...
for Loop with Python range() In Python, the range() function returns a sequence of numbers. For example, # generate numbers from 0 to 3 values = range(0, 4) Here, range(0, 4) returns a sequence of 0, 1, 2 ,and 3. Since the range() function returns a sequence of numbers, we...

One Line for Loop in Python The simplified “for loop” in Python is one line for loop, which iterates every value of an array or list. The one line for the loop is iterated over the “range()” function or other objects like an array, set, tuple, or dictionary. ...
1.for-loop和列表 在开始使用 for 循环之前,你需要在某个位置存放循环的结果。最好的方法是使用列表(list),顾名思义,它就是一个按顺序存放东西的容器。如 何创建列表: hairs = [‘brown’, ‘blond’, ‘red’] eyes = [‘brown’, ‘blue’, ‘green’] ...
