File operations in Python

Simple operation of files

1. File opening
   wenjian = open('wenjian', encoding='utf-8')
2. File reading
   wenjian = open('wenjian',encoding='utf-8')#File relative path, file encoding
   data = wenjian.read()#Read the content of the file
   print(data)
   print(wenjian.readable( ))#Whether the file is readable
   print(wenjian.readline())
   wenjian.close()
3. File writing
   wen = open('wenjian','w',encoding='utf8')
   data= wen.write('Can you write in')
   print(data)
   wen.close()#This is after the file operation , to free memory
4. Can read and write
   wenjian = open('wenjian','r+',encoding='utf8')
   data1 = wenjian.write('afsdg') wenjian.close
   ()
   wenjian = open('wenjian','r',encoding ='utf8')
   data = wenjian.read()
   print(data)
