Write a Python program to open the file hello.txt used in question no 6 in read mode to display its contents.

Q. Write a Python program to open the file hello.txt used in question no 6 in read mode to display its contents. What will be the difference if the file was opened in write mode instead of append mode?

Answer :-

f = open("hello.txt","r")
x = f.read()
print(x)  
  

If file is open in write mode then the older containt of file will remove automatically while if file is open in append mode then the older data will not delete.
