programs. At this time, the systematic consideration of the idea is a good choice. The basic Python tutorial has a lot of examples behind this book, and it's a good time to write those examples. In addition, there must be a large number of nouns at the beginning to understand. Encounter do not understand the noun as far as possible on the Internet to check, to know the question can also. Do not accumulate

This set of Python learning roadmap for everyone, follow this tutorial step by step learning, will certainly have a deeper understanding of Python. Maybe you can enjoy python 's easy-to-learn, streamlined, open-source language. T

...)3.1.4. ListsThe sequence as one of the basic Python formats is fantastic. Here are some simple examples of how to use the list.Defining a sequence that looks a bit complicated is actually not complicated.LST = [0, 1, 2, 3, 4, 5, ' A ', ' B ', [8, 888], ' 9 ', {' 10 ': 10, 10:100}]LST[1] # 11 integersLST[8] # [8, 888] a sequenceLST[9] # ' 9 ' a stringLST[10] # {' 10 ': 10, 10:100} A dictionaryIt seems to be very flexible, it is so capricious.Slice
