Question

Write a function pretty_print, which takes one parameter that can be any type of namedtuple. It "pretty prints" the contents of the namedtuple, including both the names of its fields and their values. This is subject to a few rules.

• Each field and its value are displayed on one line, with the name of the field appearing first, followed by a colon and a space, followed by the value of the field converted to a string.
• The fields should be displayed in the same order that they were specified when the namedtuple's type was created.
• The field names should have "padding" (i.e., empty space) in front of them, so that the colons all line up vertically; only the fields that have names longer than all of the others should have no spaces in front of their names.

A couple of examples follow.

>>> from collections import namedtuple
>>> Point = namedtuple('Point', ['x', 'y', 'z'])
>>> pt = Point(z = 5, x = 9, y = 13)
>>> pretty_print(pt)
x: 9
y: 13
z: 5
>>> Person = namedtuple('Person', ['name', 'age', 'favorite'])
>>> instructor = Person(name = 'Alex', age = 45, favorite = 'Boo')
>>> pretty_print(instructor)
    name: Alex
     age: 45
favorite: Boo

Answer 1

Code:

from collections import namedtuple
def pretty_print(pt):
for i in range(len(pt)):#this loop iterates untill the len of pt
print(pt._fields[i],":",pt[i])#here we print the output in the format

  
Point = namedtuple('Point', ['x', 'y', 'z'])
pt = Point(z = 5, x = 9, y = 13)
pretty_print(pt)

Person = namedtuple('Person', ['name', 'age', 'favorite'])
instructor = Person(name = 'Alex', age = 45, favorite = 'Boo')
pretty_print(instructor)

Output:
