Sir aap views aur subscribers par maat jaana, please aise hi content bnate raho. You are the best in the world. Under your guidance I think I will become a good Data Scientist. Keep me in your light sir. I wish to grow such that I can call you as my first mentor at a very big stage.

[sarthakkaushik]

Your videos are so underated. These videos are actually GOLDMINES !!

When using the json.dump() or json.dumps() functions in Python, tuples are converted to lists in the resulting JSON output. This is because JSON does not have a built-in tuple data type.

JSON supports a limited set of data types, including strings, numbers, booleans, arrays (lists), and objects (dictionaries). Since tuples in Python are immutable and ordered sequences, they don't have a direct equivalent in JSON.

To represent the data from a tuple in JSON, it is converted to a list, which is the closest JSON equivalent to a tuple. This allows for preserving the order of elements and accessing them using numerical indices, just like in a tuple.

Thank's Bhaiya ji mai Internship kar rha tha but due too sem exam I have to drop my session so I missed more topics but this file handling all topics totally matched by those mentor teach other student .So thank's bhaiya for more knowledge... I belongs a middle class family but this channel is more helpful for me and you are my elder brother.... One more request bhaiya ji Please make a playlist for Tableau please bhaiya

awesome itana acche content mujhe to nahi mila kisi or you tube video me

At 40:46, alternate lines are getting printed because:
the first f.readline() just checks if the loop should continue and it does not prints anything. The second f.readline() is printing the next line. And it goes on. Therefore only alternate lines are getting printed

[deepikaballa]

Sir, I rarely comment and like videos. But for the first time i felt commenting all your videos . Thankyou for sharing topics with depth 🙏

[nikhil.moharir]

Starting from small and simple examples to advance step by step, usage of simple variables and keywords and explaining each and every type in simplest way possible makes your videos a hidden gem. You have made this concept so easy to understand that I have shared your videos with my classmates. Thank you so much for your efforts.🙏😇

with open("file.txt", 'r') as fin:
chunk_size = 100
while 1:
s = fin.read(chunk_size)
if not s:
break
print(s)

[hemujagwan]

treasure for data science aspirants. .. thank you, 🙏🙏 sir

[qurashishebi]

In 1:24:05 you said JSON full form is JavaScript On Notation but JSON stands for JavaScript Object Notation. Koee baat ni mistake insaan se hee hote ha . but waise he bta deya . Love from Pakistan.

[flakky]

1:31:26 Nó way sir
mai yha tk áá gaya and didnt éven realise...Áap bést ho<<<333

[prashantmaurya]

Great content and explaination but there is a faulty code at 1:01:31 the correct code would be:
with open('big.txt', 'r') as f:
chunk_size = 10
while True:
reading = f.read(chunk_size)
if len(reading) > 0:
print(reading, end='***')
else:
break

[sujithsaikalakonda]

Very interesting and great explanation sir

[kom_senapati]

1:24:53 Isnt serialisation is process of converting objects into byte stream which will be stored in binary files!!!!

[yashshrivastava]

#Just a better code to read multiple lines without the if condition
for i in f.readlines():
print(i, end='')

[AnujKumar-pvci]

Sir please add project video on website

[ashisharora]

Hello sir...what if object is inherited from other class so in that case if we pickled that file in a binary format and sent it to another system. Will that system now be able to access that object since some of its functionality is dependent upon the parent class?

[amrinakter]

can I enroll now to see the paid session?

[RupeshSingh]

At 43:00, what if you are having an empty line then there is a content. It will break the code. Do you have something which is a generic approach to avoid such issues.
