In the example for Adding thousands separator, you forgot to add the "...":

>>> a = 10000000
>>> print({0:,}.format(a))
  File "<stdin>", line 1
    print({0:,}.format(a))
             ^
SyntaxError: invalid syntax

It should be:

>>> a = 10000000
>>> print("{0:,}".format(a))
10,000,000

Also, try to avoid using print as much as possible. Since most of the examples come from the interpreter itself, it is enough to just use the variable or expression:

>>> # Adding thousands separator
>>> n = 10000000
>>> "{0:,}".format(a)
'10,000,000'

>>> # Rounding
>>> n = 3.1415926
>>> "{0:.2f}".format(n)
'3.14'

>>> # Showing as Percentage
>>> n = 0.816562
>>> "{0:.2%}".format(n)
'81.66%'

This is a great addition, so I will wait for you to fix this and then merge to production 🤩
