[@Lets_coding.]

Sir I practice daily your program like making list from user and write or read data etc

[@Noicceboi]

In the sample paper question, your assumption that the data in the binary file "SPORT.DAT" is in the format of a singular nested list is wrong as the data is in the format of multiple lists with one list on each line. Due to this, pickle.load(f) will only load a single list (the first list in the file) and i[0] will raise this error->TypeError: 'int' object is not subscriptable. To work around this, you need to use a while True loop with try and except statement as in the marking scheme of the sqp.

[@NikitaSharma-nikkivedvyas11]

Thank you sir for this amazing explanation 😊

[@prathamaggarwal8830]

Thank you sir, I found this topic quite confusing but your practical driven approach helped me solve my confusions . Again Thankyou ❤

Sir, can you explain the output def short(L,n): for i in range(0,4): if len(L) > 4: L[i] = L[i] + L[i] else: L[i] = L[i] Sub = ["CS", "PHYSICS", "CHEMICAL", "MATHS"] short(Sub, 5) print(Sub)

[@vaibhavjha9318]

Bhai oswal sample paper ka question h na last year ka?

[@StudyNow-vc8dq]

@@vaibhavjha9318 last year ka he

[@Protongirl6289]

First thing input was last=['CS','HINDI','PHYSICS','CHEMISTRY','MATHS'] Therefore, len(l)>4 so if wala condition apply hoga replicate ho jaayega list ka har element as L[i]+L[i] hai Hence, OUTPUT- ['CSCS','HINDIHINDI','PHYSICSPHYSICS','CHEMISTRYCHEMISTRY','MATHSMATHS']

sir you dont use try except , in marking scheme it is told that there is half mark for try except block

[@HimanshuSingh-497]

(Please koi solution bata do)A text file "file.txt" has some text. Write a program in Python which should read each word or line of that file and count and display the occurrence of word File and Data

[@LivingInSpace]

count=0 def findOccurr(): findword=input("Enter line") file=open("abcd.txt","r") line=file.readlines() for i in line: if i[0]==findword: count+=1 print(count)

Sir, can you explain the output def short(L,n): for i in range(0,4): if len(L) > 4: L[i] = L[i] + L[i] else: L[i] = L[i] Sub = ["CS", "PHYSICS", "CHEMICAL", "MATHS"] short(Sub, 5) print(Sub)

[@Sam01_.1]

output is same as sub

[@StudyNow-vc8dq]

@jeecracker4456 no , do this in IDLE and check again

[@YugTrivediProductions]

Who didn't return the value, return L should also be there. If problem still persists then look in chat gpt to correct the code

[@StudyNow-vc8dq]

@YugTrivediProductions no bro, it is the correct code . Check the previous year board question paper
