7:37 my method

a=open('data.txt', 'r')
b=a.readlines()
print(b[-1])
a.close()

[xperthighlight]

in the question where we have to write a code to print last line of file :

you can use this code also:

f=open("1.txt", "r")
x=f.readlines()
print(x[-1])

[jaikapoor]

You don’t have to put delimiter keyword because the default delimiter is comma itself. Also, you don’t need a loop of .writerow(), you can just pass the nested list in .writerows()

This brave showing his ads like: wow! You really let this add in?😂🤦🏻.... Bro u won't be able to advertise if it wasn't for this ad 🤣

[ishankrajpal]

to print last line:
fp=open('blablabla.txt', 'r')
lines=fp.read().splitlines()
lastline=lines[-1]
print(lastline)

[rehanmomin]

7:32 code is not valid gives error.
Corrected code-
file=open('data.txt', 'r')
line=file.readlines()
last=line[-1]
print(last)

11:21 also gives error.
Corrected code-
def displayword():
a=open('Answer.txt', 'r')
b=a.read()
c=b.split()
for i in range(len(c)):
if len(c[i])>4:
print(c[i])
else:
continue

Or you could just assign and empty variable first like
a=' '
While a:
Like that but for loop is more easy. Atleast for me.

Who is wathching this right now for tomorrow's exam😅😂

[rajat]

BHAIYA I KNOW YOU TRYING TO CREATE A BULK BUT PLEASE UPLOAD ALL OF PYTHON ASAP BECAUSE WE HAVE BOARDS, PRACTICALS, AS WELL AS MAINS RIGHT INFRONT OF US, DON'T HAVE MUCH TIME LEFT HOPE U

[ishankrajpal]

to display words whose length less than 4 :
fp=open('blablabla'.txt', 'r')
words=fp.read().split()
for i in words:
if len(i)<4:
print(i)
fp.close()

[rohanranjanprasad]

Thank you bhaiya .... It's helping a lot.

[hrishikeshbharadwaj]

Aman bhaiya, , please bata do na ki aap Physics ki remaining chapter ki notes kab denge 📚📚please please reply🙏🙏 agar kisi ko pata hai please reply 🙏🙏🙏

[mayank]

In the last program, the interpreter would give an error: "local variable 'a' referenced before assignment"

To avoid this, before while loop, at line number 3, you'll have add one more line of code as follows:
a =' '

and you're all good. :)
