[@indiranamasivayam9174]

read() and readline() gives empty string. It is said in your video. I can't understand why and when that happens. It is mot clear in your video. Can you please vlarify mam

[@SwatiChawlaofficial]

To see this practically , first read all the data from the file , then again use read() and readline() function then try to print the string. It will return empty string

[@urpaps]

Thank you mam finished file handling

Great... Make sure to practice practically as well..

Can't we use for loop instead of while loop.

[@SwatiChawlaofficial]

For loop u can use..in case of nested list...my advice is to implement practically to explore... It will make ur Concepts nore clear

Uskii??

Actually... for this chr() and ord() Functions are used...to find the ascii value and the ordinal value... A=65 B=66 .... Z=90 a=97 b=98 .... z=122

[@SwatiChawlaofficial]

Ok

[@indiranamasivayam9174]

Mam in seek () and tell() I have a doubt. When you used seek() with 2 arguments like seek(6,1) you changed the mode from r to rb. That place I can't understand mam. Why can't that be done with the text file. Can't it work from current location. Why binary files alone can do that. Please explain mam.

Ma'am try and except should be in the same intend?? What if we do not write any kind of exception name in front of "except" blm?? Will it be executable?

[@SwatiChawlaofficial]

yes....try and except must be at same level.. yes...if we specify the name of the exception, it will handle only that particular exception.... but if we skip that, it will handle all types of exceptions...

[@sunitasheoran8847]

Mam I have doubt that only in binary file we have to write same no of dump and load statement if we don’t use try and except? And it is compulsory in other files except binary that we have to write same no of dump and load statement or optional

[@SwatiChawlaofficial]

yes....only in binary file we have to write same no of dump and load statement if we don’t use try and except. In other type of files except binary we don't have load() and dump()

[@parvati-putra]

ma'am even if we use 'with' then also we are getting exception error please explain this ma'am

[@kanantalwar8173]

Mam why this EOF Error occurs?

[@SwatiChawlaofficial]

While reading the data from binary file, when it reaches to the End of File, it generates the EOFError exception.. To handle that exception, we have to use try and except block...

Mam if we use nested list and append in a file then we don't need to use try and except please reply mam In exams what we use?

@@SwatiChawlaofficial ok mam thanks 😘😘😘😘

[@anushasingh5562]

This is EOF error but when EOL error occurs mam ??

[@SwatiChawlaofficial]

EOL means End of Line while reading data from a file using readline () , when EOL occurs , it returns an empty string,.....doesn't geenrate any exception..

[@anushasingh5562]

@@SwatiChawlaofficial ok mam thanks

[@Udipto_Biswas]

mam EOFError ata q hai? yeh toh balata he nahi apne. bata dijiye please

[@SwatiChawlaofficial]

EOFError is raised when one of the built-in functions input() or raw_input() hits an end-of-file condition (EOF) without reading any data. This occurs when we have asked the user for input but have not provided any input in the input box. We can overcome this issue by using try and except keywords in Python. This is called as Exception Handling.

Yes... it's always a good programming practice to close a file.. However,.if u have opened the file..using file with statement...then there is no need to close the file..
