Python实现简易过滤删除数字的方法小结

import re
L = [u'小明', 'xiaohong', '12', 'adf12', '14']
for i in range(len(L)):
  if re.findall(r'^[^\d]\w+',L[i]):
    print re.findall(r'^\w+$',L[i])[0]
  elif isinstance(L[i],unicode):
    print L[i]

L = [ 'xiaohong', '12', 'adf12', '14',u'晓明']
for x in L:
  try:
    int(x)
  except:
    print x

L = [ 'xiaohong', '12', 'adf12', '14',u'晓明']
#对于python3来说同样还可以使用string.isnumeric()方法
for x in L:
  if not x.isdigit():
    print x
