Reading python documentation in the terminal?

Question

Is there a way to install the python documentation that would make it available as if it was a manpage? (I know you can download the sourcefiles for the documentation and re

You can use help(Class-name/method-name/anything). But also using __doc__

A special __doc__ docstring is attached to every class and method. For example look what i typed into my interpreter.

>>> print(str.__doc__)
str(object='') -> str
str(bytes_or_buffer[, encoding[, errors]]) -> str

Create a new string object from the given object. If encoding or
errors is specified, then the object must expose a data buffer
that will be decoded using the given encoding and error handler.
Otherwise, returns the result of object.__str__() (if defined)
or repr(object).
encoding defaults to sys.getdefaultencoding().
errors defaults to 'strict'.
>>> print(int.__doc__)
int(x=0) -> integer
int(x, base=10) -> integer

Convert a number or string to an integer, or return 0 if no arguments
are given.  If x is a number, return x.__int__().  For floating point
numbers, this truncates towards zero.

If x is not a number or if base is given, then x must be a string,
bytes, or bytearray instance representing an integer literal in the
given base.  The literal can be preceded by '+' or '-' and be surrounded
by whitespace.  The base defaults to 10.  Valid bases are 0 and 2-36.
Base 0 means to interpret the base from the string as an integer literal.
>>> int('0b100', base=0)

It even works for modules.

>>> import math
>>> math.__doc__
'This module is always available.  It provides access to the\nmathematical functions defined by the C standard.'
>>> math.ceil.__doc__
'ceil(x)\n\nReturn the ceiling of x as an Integral.\nThis is the smallest integer >= x.'
>>> 

Since every class has a __doc__ which is a docstring attached to it you can call it using the class_name.__doc__

>>> print(ord.__doc__)
Return the Unicode code point for a one-character string.
