Repr() function - Valentina - Aug-19-2019

Hello! I am a Junior in Python. I am doing my first steps.
Please help with repr(function).
I read in Python book that repr() must return "real" meaning.
For example (from book):
>>> num = 1 / 3
>>> repr(num)#
‘0.33333333333333331’
>>> str(num) #
‘0.333333333333’

I tried to use repr() in Sublime Text Editor and in interactive python mode/ But result is same. I receive only 0.333333333333, but never ‘0.33333333333333331’.
I use Python 3.7.2 ver.

Thank you very much for support!
Valentina!

Quote:Return a string containing a printable representation of an object. For many types, this function makes an attempt to return a string that would yield an object with the same value when passed to eval(), otherwise the representation is a string enclosed in angle brackets that contains the name of the type of the object together with additional information often including the name and address of the object. A class can control what this function returns for its instances by defining a __repr__() method.

fishhook provided comprehensive answer, but you can always start from built-in help and work from that. In many cases built-in help is all you need.

>>> help(repr)
Help on built-in function repr in module builtins:

repr(obj, /)
    Return the canonical string representation of the object.
    
    For many object types, including most builtins, eval(repr(obj)) == obj.
