18:00, ma'am yaha pe write function use ke wajah se data file me overwrite hona chahiye tha na, phir vo list ki tarah kaise store kiya, write () to overwrite karta hai na?

[@TECHQueenLovejeetArora]

write() overwrite nahi krta, W mode Overwrite krta hai, write() to only ek Function hai.

plz hlp me mam mera load data file show nhi horhi only dump wali hi show ho rhi h

[@AYArchanaYadav]

Hi Ekta, Here is the correct program
import pickle
def bfile():
bfile=open("p.txt","wb")
pickle.dump("hii my name is ekta",bfile)
pickle.dump(28888,bfile)
pickle.dump({"w":34,"r":45},bfile)
bfile()
def bfile_2():
bfile_2=open("p.txt","rb")
try:
while True:
data=pickle.load(bfile_2)
print(data)
except:
bfile_2.close()
bfile_2()
There were 2 mistakes while True hoga na ki true, and second print(data) me indent aayega, else vo loop k bhaar jaa k print. That means kuch print ni hoga
