This article mainly shows you "python how to achieve file operation", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "python how to achieve file operation" this article.

General content of file operation:

# File operation # Open file open open an existing file or create a new file open ('. / Test.txt','w')

# File operations # Open file open open an existing file or create a new file fobj=open ('. / Test.txt','w') # pass it to an object to manipulate it through an object # start operation read / write operation fobj.write ('there is a flock of seabirds on the vast sea') fobj.close () # Save and close

# Operation of file # Open file open, open an existing file or create a new file fobj=open ('. / Test.txt' 'w') # pass it to an object to operate on it through the object # start the read / write operation # fobj.write (' there is a flock of seabirds on the vast sea') fobj.write ('break through the storm') # the file will be overwritten fobj.close () # Save and close

# File operation # Open file open open an existing file or create a new file # default encoding is the best habit of gbk Chinese encoding is that we specify an encoding when we open a file # give him an encoding type fobj=open ('. / Test.txt','w' Encoding='utf-8') # pass it a = to an object to operate on it through the object # start the read / write operation fobj.write ('there is a flock of seabirds on the vast sea') fobj.write ('break through the storm') # the file will be overwritten fobj.close () # Save and close # write data fobj=open in binary form ('Test.txt'') 'wb') # str-- > bytesfobj.write (' no more canals between the sea '.encode (' utf-8')) fobj.close ()

Fobj=open ('. / Test.txt','w') fobj.write ('there is a flock of seabirds on the vast sea') fobj.write ('break through the wind and waves') # file existence will be overwritten fobj=open ('Test.txt','a') # add fobj.write (' between dark clouds and sea') fobj.close ()

# read data operation f=open ('Test.txt','r') # print (f.read ()) # read out print (f.read (10)) from beginning to end # specify the number of reads print (f.read ()) # read the first behavior plus parameters, and output the rest of the lines

F=open ('Test.txt','rb') data=f.read () print (data) print (data.decode (' gbk')) f.close () # File object needs to be closed

# with context management object # advantage automatically release open associated object with open ('Test.txt','r') as f: print (f.read ())
