How to find dictionary values ​​in a list?

Question

Python

We have a dictionary a={001:'1',010:'2',011:'3'}
and a list b=[0,1,0,0,0,1,0,1,1] the task is to split the list three elements each (those 0,1,0-010 and so on) and the value of this triad was searched for in the dictionary a, by value?
result:
213

Answer 1

Your task is strange. Not to mention, the number 001 as a dictionary key will cause a syntax error.

a = {'001': '1', '010': '2', '011': '3'}
b = [0, 1, 0, 0, 0, 1, 0, 1, 1]
for i in range(0, len(b), 3):
  print(a[''.join([str(b[i]), str(b[i + 1]), str(b[i + 2])])])
