Python - Convert NamedTuple to Dict to NamedTuple

DictToNamedTuple

# tested on python 3.6
from typing import NamedTuple

class T(NamedTuple):
  a: int
  b: str

if __name__=='__main__':
  
  # define a named tuple object
  t = T(20, 'Hello')
  
  # to ordered dict
  t1 = t._asdict()
  assert(t1 == t)
  
  # back to namedtuple
  t4 = T(**dict(t._asdict()))
  assert(t4 == t)
  
  # or with string class evaluation
  t5 = eval('T')(**dict(t._asdict()))
  assert(t5 == t)
