python3: module 'string' has no attribute 'maketrans'

[richardklingler]

When I run the example I get:

Traceback (most recent call last):
  File "test.py", line 1, in <module>
    import ripyl
  File "/usr/local/lib/python3.7/dist-packages/ripyl-1.2.1-py3.7.egg/ripyl/__init__.py", line 24, in <module>
    import ripyl.cython
  File "/usr/local/lib/python3.7/dist-packages/ripyl-1.2.1-py3.7.egg/ripyl/cython/__init__.py", line 82, in <module>
    cy_module_names = find_cy_modules()
  File "/usr/local/lib/python3.7/dist-packages/ripyl-1.2.1-py3.7.egg/ripyl/cython/__init__.py", line 39, in find_cy_modules
    trans = string.maketrans('/\\', '..')
AttributeError: module 'string' has no attribute 'maketrans'

Apparently maketrans doesn't exist anymore...
this is with python 3.7.3 on Debian 10.9
