#3 Reading Data From Text Files | File Handling in Python | Class 12 CBSE Computer Science
Welcome to the Part 3 of the Chapter File Handling for class 12 CBSE Computer Science .
In this video I have discussed how to read data from text files in Python. For reading data from a text file, the file must be created before extraction. After creating the file ,data from the file is being extracted and displayed using the functions read( ) , readline() and readlines( ) .

Topics:
Basic Concept of Reading from files
File modes for reading data from text files
read mode (r)
read and write mode (r+)
Functions used for reading data from text files:
read( ) in python
readline( ) in python
readlines( ) in python
Applications of read( ):
python program to read first 7 bytes from a file
python program to read first 3 bytes from a file and then another 5 bytes from the last read position
python program to read entire content from a file
python program to display the size of a file in bytes
Applications of readline( ):
python program to read the first 2 lines from a file
python program to read a complete file line by line
Applications of readlines( ):
python program to read the first 2 lines from a file
python program to read and display the last line from a file
python program to count the number of lines from a file
While implementing the practical programs in Python , I have used Spder IDE and textedit text editor , you can use any IDE and text editor of your choice.
