Welcome to Python Programming!

f = open("ABC.txt", "r",)
size = len (f.read ())
print (size)
data = f.read(5)
print(data)

Output :-

30

>>> 

Explanation :-

size = len (f.read ()) give output 30 because ABC.txt contains 30 characters.

data = f.read(5) give no output because after size = len (f.read ()) statement the pointer go to last point of txt file.
