Python Files

2. What is a file? A file is a data that remains in the system storage tool. Python provides two methods of files such as text file and binary file. Text files are simple files, whereas the binary files include binary information. Both humans and systems can read text files. In contrast, binary files can be read by the only system. How to generate a file? Python enables us to generate the file. With open () we can generate a file. This function takes three parameters. The file that we need to open and the type of procedure or permission, we require to do it on the document and buffer.

3. BufferingWhen the buffering cost collection to zero, no buffering happens. But if its collection to one, when approaching the file, buffering the file. It is generally buffering action occurs if the buffering cost is higher than one. If it is negative, the buffer estimate is the framework default.Syntax:f = open (file_name, access mode, buffering)

4. Examplef = open (itguru.txt, w+)Hence, ‘W’ represents write mode, and ‘+’ can generate the document if it does not exist in the library. The other function that can be completed with the list is ‘r’ for reading and ‘a’ for append. If we utilize the ‘+’ sign to generate the document if it does not endure in the directory.How to write data into the file?Since we have generated the file, it is period to insert the information into the file. Therefore, we should insert the first 10 number in a list.

5. Examplef = open (“balajee.txt”, “w+”)for i in range(10):f.write(” %d\r\n” % (i+1)) Output 1 2 3 4 5 6 7 8 9 10

6. How to close the file?We can close the file with the following syntaxSyntaxf.close()We can implement some other operations on the file.

7. We can implement some other operations on the file.
