sys.argv and sys.exit
It appears there is no translation of sys.argv and sys.exit. Without these it isnt possible to transpile CLI scripts that use args or have exit codes.
Test [FAIL]
Hi there, I was giving a try, but I was a bit unfortunate.
I use rbenv and pyenv
python --version
Python 3.6.10
ruby --version
ruby 2.5.4p155 (2019-03-13 revision 67245) [x86_64-darwin18]
I tried several different version of python and ruby but still failing

Instructions
Hi,
could you please add more instructions how to use it?
Thanks
byte literals not supported
b'a' are emitted as is, causes a syntax error in the ruby
range with step doesnt stop before stop
for i in range(0, 10, 2):
print(i)should emit 2->8, stepped by two
The transpiler emits
for i in 0.step(10, 2)
print(i)
endwhich emits 2->10, stepped by two
Bare except catching failure
The follow (bad) Python will catch the exception
try:
raise Exception("foo")
except:
print("Got it")It is transpiled as
begin
raise Exception, "foo"
rescue
print("Got it")
endThat only catches the default Ruby exception StandardError.
To catch the exception in Ruby, it needs to catch the top level Ruby exception class.
begin
raise Exception, "foo"
rescue Exception
print("Got it")
end🎉
Hello.
Today I use py2rb for the first time to translate some Python scripts into Ruby.
I think this tool is very useful.
Keep up your great work 🎉
Syntax error in maths
gap = max(1, floor(gap / 1.25))is transpiled to
gap = (1, floor(gap / 1.25.to_f)).maxerror:
syntax error, unexpected ',', expecting ')'
Bug when using py2rb
I just found your package and it seems to be a good one.
I installed it and tried to run it but I just found this error message on my terminal:
$ py2rb python.py
Traceback (most recent call last):
File "/usr/local/bin/py2rb", line 7, in <module>
from py2rb import main
File "/usr/local/lib/python2.7/site-packages/py2rb/__init__.py", line 2919
print('Try : ' + py_path + ' -> ' + output + ' : ', end='')
^
SyntaxError: invalid syntaxThe contents of my python.py file:
result=0
a,b=0,2
for x in range(1500):
a,b=b,a+(4*b)
if a<4000000:
result+=a
print(result)Can you help me?
Upper case variable names in functions causes ruby error: dynamic constant assignment
Python
def f():
CODES = {"KEY": 1}
return CODESbecomes
def f()
CODES = {"KEY" => 1}
endRuby complains that CODES is a constant, when it was a local variable in Python.
foo.rb:2: dynamic constant assignment
CODES = {"KEY" => 1}
AnnAssign not supported
ast.AnnAssign proves typed assignments (a: int = 1).
It is slightly different structure from ast.Assign as there is only one target instead of an array of targets, and includes an annotation which could be ignored initially.
only two ok

Support for Python 3.8
Hi, thanks for this great project!
When trying to translate a simple script with Python 3.8, the constants are missing.
print(1 + 2)outputs
Warning : syntax not supported (<_ast.Constant object at 0x10c4da040>)
Warning : syntax not supported (<_ast.Constant object at 0x10c4da2e0>)
print( + )It looks like there were changes in ast for Python 3.8. From the docs:
Changed in version 3.8: Class ast.Constant is now used for all constants.
Deprecated since version 3.8: Old classes ast.Num, ast.Str, ast.Bytes, ast.NameConstant and ast.Ellipsis are still available, > but they will be removed in future Python releases. In the meanwhile, instantiating them will return an instance of a different > class.
There's also an unrelated warning about YAML.
/usr/local/lib/python3.8/site-packages/py2rb/__init__.py:29: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
