如果我只想匹配字母单词，如何在Python中使用re.compile

Question

I'm learning the RE module for Python and doing some experiment. I have question regarding using expression, here is the example:

name = 'abc123def456'
m = re.compile('.*[^0-9]').match(name)
m.group()
print m

Result is 'abc123def'

What should I do if I want to totally take out the numeric number

Thank you!

You can extract all occurrences of alphabets and concatenate them to get just the alphabets in the string. See below:

"".join(re.findall("[a-zA-Z]+",name))
