Problem Statement: Python program to read a program from another file.

Problem Description: We need to read the contents from a python file in a program and print its content.

We will use the concepts of file handling in python and read and print a program from a file .

Program to illustrate the program

Main.py:

F=open("HirarchicalInheritance.py","rb")

data=F.read(20)
print(data.decode())
print("==================")

F.seek(40,1) # 1 current position ..move pointer to 60th position
data=F.read()
print(data.decode())

F.close()

HirarchicalInheritance.py:

F=open("HirarchicalInheritance.py","rb")

data=F.read()
print(data.decode())

F.seek(10,0) # 0 begin of file..Move Pointer to 10th Position
data=F.read()
print(data.decode())

F.seek(-40,2) # 2 end of file
data=F.read()
print(data.decode())

Output:

F=open("HirarchicalInheritance.py","rb")

data=F.read(20)
print(data.decode())
print("==================")

F.seek(40,1) # 1 current position ..move pointer to 60th position
data=F.read()
print(data.decode())

F.close()
