Python simple Text Processing method

The examples in this paper describe the method of simple text processing in Python. Share to everyone for your reference. Specific as follows:

Because of the multi-threading impact, the C + + project printed out in an inconsistent chronological order, resulting in a less-than-good statistic in Excel, and using Python to write a paragraph script to solve it. involves the following aspects

1. txt text read, UTF8 processing
2. Basic operation of strings
3. Basic operation of Dict
4. Basic operation of List (array)
