fileObj.close(): Flush and close the file stream.You can optionally specify the text encoding via keyword parameter encoding, e.g., encoding="utf-8". You can also use 'rb', 'wb', 'ab', 'rb+' for binary mode (raw-byte) operations. The available modes are: 'r' (read-only - default), 'w' (write - erase all contents for existing file), 'a' (append), 'r+' (read and write). open( file, ) -> fileObj: Open the file and return a file object.Python provides built-in functions and modules to support these operations. Open the file for read or write or both.If you are new to Python programming, I highly recommend this book. Open file for reading and writing (truncates files) Open file for reading and writing (appends to end) Open file for writing (will truncate file) # and append (add line) at the end of the file. # The 'a' flag tells Python to keep the file contents If you simply want to add content to the file you can use the ‘a’ parameter. That is to say, if the file contents exists it will be replaced. The ‘w’ flag makes Python truncate the file if it already exists. The code below creates a new file (or overwrites) with the data. Python Programming Bootcamp: Go from zero to hero write() method with a parameter containing text data.īefore writing data to a file, call the open(filename,’w’) function where filename contains either the filename or the path to the filename. Python supports writing files by default, no special modules are required.
