f=open("myfile.txt",'w')
f.write("Data insert into the file")
f.close()

#open file in read mode
f=open("myfile.txt",'r')
data=f.read()
print(data)
print(type(data))
f.close()

output-

Data insert into the file

-In this program, initially we open the file named as 'myfile.txt' and 'txt' is shows that file is of type 'text',
-then by f.write("Data insert into the file") we write this string into the file.
-then by f.read() we get the all text of the file then we print that.
