如何根据特定的字符串匹配将特定字符串附加到另一个字符串？

Question

I need to append _123 if name has _abc_0 or _abc_1 or _abc_# where # is any number of digits . How can I write it in if condition?

name = "name_abc_0_any_chars"
if "_abc_<#any digit>" in name: #not sure what to write in place of <#any digit>
    name = name + "_123"
print "name: ", name

Output:

name: name_abc_0_any_chars_123

Answer 1

For a solution without regex, you could use the any() function. Eg

a = ['_abc_0', '_abc_1', '_abc_2', '_abc_3', '_abc_4', '_abc_5', '_abc_6', '_abc_7', '_abc_8', '_abc_9']
name = "name_abc_34_other_characters"

if any(x in name for x in a):
    name += "_123"

print("name: ", name)

Output:

name:  name_abc_34_other_characters_123

Answer 2

Edited

If you want to test if a variable contains _abc_#d , use re :

import re

name = "name_abc_0_any_chars"
if re.findall('abc_\d+', name):
    name += '_123'

Output:

'name_abc_0_any_chars_123'
