How to convert numbers to words using Python?

The constructor for the string class in python, ie, str can be used to convert a number to a string in python. For example,

i = 10050
str_i = str(i)
print(type(str_i))

This will give the output:

<class 'str'>

But if you want something that converts integers to words like 99 to ninety-nine, you have to use an external package or build one yourself. The pynum2word module is pretty good at this task. You can install it using

$ pip install pynum2word

Then use it in the following way

>>> import num2word
>>> num2word.to_card(16)
'sixteen'
>>> num2word.to_card(23)
'twenty-three'
>>> num2word.to_card(1223)
'one thousand, two hundred and twenty-three'
