how to replace two arrays that have different values into the same value between the two arrays?-CodePudding

I'm learning python arrays and I'm having trouble solving this code

a = [1,2,3,4,5]
b = [6,7,8,9,10]

a = b
print(a)
print(b)

I want to change the value of array b to be the same as the value of array a. like this:

a = [1,2,3,4,5]
b = [1,2,3,4,5]

but the result is like this:

a = [6,7,8,9,10]
b = [6,7,8,9,10]

what I want is the value of a is equal to b not vice versa. can you help me to solve this?

CodePudding user response：

you are assigning in the different order. You would like to assign list b to the value a not the other way around. But as lists are mutable, I would suggest doing

b = a.copy()

Otherwise you would modify b when you modify a.

CodePudding user response：

If you want your output, you can also try: b = a

CodePudding user response：

If I am getting you correctly you can use:

b = a.copy() # as mentioned in other comments

#or

b = a[:]

This way the value of a will be assigned to b. At the same time if you change any of them the other one will not change.
