Python File - Handling

Python supports different types of file handling options, to operate on file, which is given below:

 

  • r - It is used for reading the file.

  • w - It is used for writing the file.

  • a - It is used for appending the file.

  • r+ - It is used for both reading and writing the file

 

If you do not pass any option then it works by using r option(By default)

 

Here we can learn it with the help of some codes of lines –

Read Option

“r” option is used to read file

>>> File = open(“filename”, “r”)

.

.

File.close()

Write Option

“w” option is used to read the file

>>> File = open(“filename”, “w”)

.

.

File.close()

Append Option

“a” option is used to read the file

>>> File = open(“filename”, “a”)

.

.

File.close()

Open file using “with” option and “write” into the file

>>>  with open(“filename”, “w”) as f:

                f.write(“hello naveen”)

Split lines using file hadling

To perform this we have used the split() function with filehandling

>>>  with open(“filename”, “r”) as f:

                for line in f:

                   data = line.readlines()

                    result = data.split()

                f.write(“hello naveen”)
