(i)
| Text files | Binary Files |
|---|---|
| Extension is .txt | Extension is .dat |
| Data is stored in ASCII format that is human readable. | Data is stored in binary form (0s and 1s), that is not human readable. |
(ii)
def Searchtype(mtype):
fobj = open("CINEMA.DAT", "rb")
try:
while True:
data = pickle.load(fobj)
if data[2] == mtype:
print("Movie number:", data[0])
print("Movie Name:", data[1])
print("Movie Type:", data[2])
except EOFError:
fobj.close()
