So I found this on stack overflow
In [2]: import string
In [3]: identity = string.maketrans("", "")
In [4]: x = ['+5556', '-1539', '-99', '+1500']
In [5]: x = [s.translate(identity, "+-") for s in x]
In [6]: x
Out[6]: ['5556', '1539', '99', '1500']
but it fails in my file, due to I believe mine being a list of list. Is there
an easy way to iterate the sublists without flattening?
Current code.
input_table = [[item.strip(' "') for item in record.split(',')]
for record in text_file.splitlines()]
# At this point look at input_table to find the record indices
identity = string.maketrans("", "")
print(input_table)
input_table = [s.translate(identity, ",'") for s
in input_table]
