This article introduces the knowledge about "how to use list in Python". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

list, Chinese can be translated into a list, is used to deal with a group of ordered items of data structure. Think of your shopping list, to-do list, phone address book, etc., as a list. It's not exactly new, because we've used it before, in this sentence:

for i in range(1, 10):

#Skip a few lines here

Do you see where the list is? Try this:

print range(1,10)

The result is:

[1, 2, 3, 4, 5, 6, 7, 8, 9]

This is a list. It is generated by range. Write the above for loop statement as:

l = range(1, 10)

for i in l:

The effect is the same.

So you can see that what the for loop does is it iterates through every item in a list, assigning the current item to a variable (here i) each time it loops through until the list ends.

We can also define our own list, which is a set of values surrounded by brackets and separated by commas:

l = [1, 1, 2, 3, 5, 8, 13]

You can print this list:

print l

It can also be used for... In iterates through the list, outputting each item in turn:

for i in l:

print i,

The elements in the list can also be of other types, such as:

l = ['meat', 'egg', 'fish', 'milk']

Even a mixture of different types:

l = [365, 'everyday', 0.618, True]
