Printing array with reference
Can someone explain me why it is 7? lst1 = [1,2,3,4] lst2 = lst1 lst1  = 7 print(lst2 )
lst1 = [1,2,3,4] lst2 = lst1 lst1  = 7 print(lst2 ) # list1 has a list of elements assigned to it # list2 has assigned list1 so it has same elements as list 1 # list1=7 it assign list1 1st element to 7 # list1 and list2 are same so when we update list1 the elements of list2 is also updated so 7 overwrite in both the list at 1st element # print(list2) it print the 1st elements at list2 which is 7 due to overwrite so finally the output is 7
I don't know python, but I know few other languages, so I might be wrong, arrays are stored with references , only one copy is shared with all , hence modifying one changes all the copies this concept is common in most of the languages
thanks everyone, now I get it 😀
