Manipulate files with python
Step one; locate the file, open the file
Step II; modify a file, read the file
Step three; close the file, and save
With the following code demonstrates;
Open F = 1. (File NAMA)
2. reached, f.read (read byte #) # do not write all the read default write method f.write (Data)
3.f.close # close and save the
read real column;
f = open(file = 'C:\\Users\\Public\\heloo',mode="w"，encoding='utf-8')
f.write('欢迎\n')
f.write('xiaoma\n')
f.close()

Open = F (File = 'C: Public \\ \\ \\ heloo the Users', MODE = 'R & lt', encoding = 'UTF-. 8')
Print (reached, f.read ())
f.close ()
