Use of X.shape[0] here?

#1

what is the Use of X.shape[0] here?
please help

#2

hey @vidit123 ,
are you referring to the one used for splitting ?

#3

Yes Prashant, I didn’t get that

#4

so ,
X is actually a numpy array , means it will be having some shape
a shape (n,m) represents
n = number of records
m = number of columns

so as we need to split in 80:20 ratio , means 80*n:20*n
So , just doing x.shape[0] , will work something like (n,m)[0] , returning only n.

in this way we can use this value to create the splits in the data ( by getting the actual proportion )

I hope this helps.
