Testcase ( read all ) :

>> from Bopen import bopen         # Importing the function
>> file = bopen("exmaple.txt", "r")# open up a file
>> data = file.read()               # Read all bytes within it
>> file.close() # Closing the file # Close the file
>> print(data) 

Output :

) lanif ( 3 enil ) gnihtemos ( 2 enil ) enil tsrif( 1 eniL

Testcase 2 ( 5 bytes ):

>> from Bopen import bopen         # Importing the function
>> file = bopen("exmaple.txt", "r")# open up a file
>> data = file.read(5)             # Read 5 bytes within it
>> file.close() # Closing the file # Close the file
>> print(data) 

Output :

eniL
