The namedtuple function can be used to create a named tuple or class, which can be more effective for debugging code. Here’s an example:
from collections import namedtuple
# Create a class
a = namedtuple('c', ('name', 'age'))
x = a('perror', 21)
# Access via object method
print(x.name)
print(x.age)
# Access via indexing
print(x[0])
In addition to inheriting methods from normal tuples, named tuples have three additional methods: the _fields class attribute, make() class method, and _asdict() class instance method.
Here’s how to use these methods:
# View all fields in the named tuple
print(x._fields)
# `_make` generates a class instance using an iterable object
s = ('perror', '21')
new_s = x._make(s)
# Print the tuple's fields in a more friendly format using the class instance method
print(new_s._asdict())
Note that after the named tuple is created, its elements can be accessed either by attribute name or by indexing.
