Python How to print list to list

Question

I have meet a problem of multiple output.

product_list=['Salted Egg Grade A','Salted Egg Grade B','Salted Egg Grade C']
price_list=['30','27','24']
for x in product_list:
  for y in price_list:
    print(x +": "+ y)

what I expected is

Salted Egg Grade A: 30
Salted Egg Grade B: 27
Salted Egg Grade C: 24

What I am getting is

Salted Egg Grade A: 30
Salted Egg Grade A: 27
Salted Egg Grade A: 24
Salted Egg Grade B: 30
Salted Egg Grade B: 27
Salted Egg Grade B: 24
Salted Egg Grade C: 30
Salted Egg Grade C: 27
Salted Egg Grade C: 24

Is there any solution to solve this?

Answer 1

You can use zip

product_list=['Salted Egg Grade A','Salted Egg Grade B','Salted Egg Grade C']
price_list=['30','27','24']
for x,y in zip(product_list, price_list):
    print(x + ": " + y)

Output:

Salted Egg Grade A: 30
Salted Egg Grade B: 27
Salted Egg Grade C: 24

Answer 2

You can also use enumerate() which basically returns the index as well as the element for each iteration. By using these indices you can loop on the other variable.

product_list=['Salted Egg Grade A','Salted Egg Grade B','Salted Egg Grade C']
price_list=['30','27','24']
for index, x in enumerate(product_list):
    print(x +": "+ price_list[index])
