[New-bugs-announce] [issue36653] Dictionary Key is without ' ' quotes

New submission from PushkarVaity <iampushkar01 at gmail.com>:

I am using Python 3.7 with anaconda install.
I am trying to write out a dictionary with similar key's.

for ex: proc_dict = {'add': ('/home/file.tcl', 'args'), 'add': ('/home/file2.tcl', 'args'), 'sub': ('/home/file2.tcl', 'args')}

To do this, I am using the following class definition and functions:
    class ProcOne(object):
        def __init__(self, name):
            self.name = name

        def __repr__(self):
            return self.name

I am writing out the dictionary in the following way:
proc_dict[ProcOne(proc_name)] = (full_file, proc_args)

Now, the dictionary key as shown in the example at top is of string type. proc_name is the variable holding this string.

The values are tuples. Both elements in the tuple are strings.

When the dictionary is finally written out, the format is as below:
proc_dict = {add: ('/home/file.tcl', 'args'), add: ('/home/file2.tcl', 'args'), sub: ('/home/file2.tcl', 'args')} 

Please note the difference from the first example.
The key values don't have a ' ' quote in spite of being a string variable type. 

Since the string quotes are missing, it is very difficult to do post processing on this dictionary key.

I am a student and I though that this is an issue because now I am not able to compare the key value with a normal string because of the missing quotes. The in or not in checking operations do not evaluate to true/false because of the missing quotes.

Please let me know if this has never been reported before as I am just a novice programmer and would be a big boost to my morale :-) 
Also, please let me know if this issue was already known or wasn't an issue at all.
