Append Only (‘a’) : Open the file for writing.The handle is positioned at the beginning of the file. For an existing file, data is truncated and over-written. Write and Read (‘w+’) : Open the file for reading and writing.Creates the file if the file does not exist. For an existing file, the data is truncated and over-written. Write Only (‘w’) : Open the file for writing.
Different access modes for reading a file are – File handle is like a cursor, which defines from where the data has to be read or written in the file.
These modes also define the location of the File Handle in the file. It refers to how the file will be used once it’s opened. Note: To know more about file handling click here.Īccess modes govern the type of operations possible in the opened file. Binary files: In this type of file, there is no terminator for a line and the data is stored after converting it into machine-understandable binary language.Text files: In this type of file, Each line of text is terminated with a special character called EOL (End of Line), which is the new line character (‘\n’) in python by default.There are two types of files that can be handled in python, normal text files and binary files (written in binary language, 0s and 1s). Python provides inbuilt functions for creating, writing and reading files.
