技術標籤：RegExpython正則表示式regex

使用python來做正則表示式：

import re

txt = "12 324 rain"

#Check if the string contains any digits (numbers from 0-9):
x = re.findall("\d", txt)
print('x 結果: ',x)

if x:
  print("Yes, there is at least one match!")
else:
  print("No match"
 
)

txt_new = 'wer asdfw rew sddf'
y = re.findall("\d", txt_new)
print('y 結果：',y)

if y:
	print("Yes, the string has digits")
else:
	print("No, there is no any digits in the string")

字元 \d: Returns a match where the string contains digits (numbers from 0-9)

結果如下：
