在Python中,可以使用input()函数来获取用户输入的元素。 # 获取用户输入的元素element=input("请输入需要重复的元素:") 1. 2. 4. 输入重复的次数 然后,我们需要输入重复的次数。同样地,可以使用input()函数来获取用户输入的次数。 # 获取用户输入的重复次数repeat_times=int(input("请输入重复的次数:")) 1. ...
Instead of adding each element one by one using the append() method, we can use the extend() method to add entire elements of the list at once to repeat them. The extend() method, when invoked on a list, accepts a list as input arguments and adds the input list to the existing lis...
To write each element of a list to a new line in a file: lines = ['First line', 'Second line', 'Third line'] with open('example.txt', 'w') as file: for line in lines: file.write(f'{line}\n') 8. Using With Blocks for Multiple Files To work with multiple files simultaneous...
