The benefit of this method is that you can print a list that stores all available types in Python. You can print a combination of int and boolean types as follows: my_list = [1, 2, 3, True, False] print(*my_list, sep=', ') Output: 1, 2, 3, True, False When using the...
join(map(str, my_list))) # Output: Numbers: 1, 2, 3, 4, 5 7. Print List Item Index and Value Python program to print the index and the items of a List using a for loop using the range() method. for i in range(len(my_list)): print("Item index is", i, "and Item is"...
值得留意,我们控制print函数行为的所有参数都必须使用关键字参数形式,而能使用位置参数形式。这个应该很好理解,因为带打印元素的个数是不确定的,比如遇到这种拆包形式*items。 >>> items = [1, 2, 3, 4, 5] >>> print(*items, sep=', ') 1, 2, 3, 4, 5 >>> ...
Imagine you want to describe your intention of buying the items on your grocery list to a friend. You might say something like, “For each item in my grocery list, I want to buy this quantity”. You can write almost the same thing in Python to loop through your Python list. Let’s...
