[New-bugs-announce] [issue37182] ast - handling new line inside a string

[Ilya Kamenshchikov]

New submission from Ilya Kamenshchikov <ikamenshchikov at gmail.com>:

parsing two different strings produces identical ast.Str nodes:

import ast

txt1 = '"""\\n"""'
txt2 = '"""\n"""'

tree1 = ast.parse(txt1)
tree2 = ast.parse(txt2)

print(tree1.body[0].value.s == tree2.body[0].value.s)
print(bytes(tree1.body[0].value.s, encoding='utf-8'))
print(bytes(tree2.body[0].value.s, encoding='utf-8'))

>>> True
>>> b'\n'
>>> b'\n'

Expected result: I should be able to distinguish between the nodes created from two different strings.
