Python parse comma-separated number into int [duplicate]

How do I use Python to convert a string to a number if it has commas in it as thousands separators?

How would I parse the string 1,000,000 (one million) into it's integer value in Python?

Solution 1:

>>> a = '1,000,000'
>>> int(a.replace(',', ''))
1000000
>>> 

Solution 2:

There's also a simple way to do this that should handle internationalization issues as well:

>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'en_US.UTF-8')
'en_US.UTF-8'
>>> locale.atoi("1,000,000")
1000000
>>> 

I found that I have to explicitly set the locale first as above, otherwise it doesn't work for me and I end up with an ugly traceback instead:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.6/locale.py", line 296, in atoi
    return atof(str, int)
  File "/usr/lib/python2.6/locale.py", line 292, in atof
    return func(string)
ValueError: invalid literal for int() with base 10: '1,000,000'
