In a real-world application, most of the process needs to read data from files and write data into files, Python provides built-in support for file handling and allows users to handle files, along with many other file handling options like mode and buffering, and encoding.
file_object = open(filename, mode, buffering, encoding)
filename: It is the name of the file or relative path of the file.
mode: It tells the program in which mode the file has to be open, type of modes are:
- r : for reading.
- w : for writing.
- a : for appending.
- r+ : for both reading and writing
buffering: Here, if the value is set to zero (0), no buffering will occur while accessing a file; if the value is set to top one (1), line buffering will be performed while accessing a file.
Working of read mode
file = open("file.text", "r")
print (file.read())
Working of write mode
file = open('geek.txt','w')
file.write("This is the write command")
file.write("It allows us to write in a particular file")
file.close()
Working of append mode
file = open('geek.txt','a')
file.write("This will add this line")
file.close()
