我已將命令的輸出存儲chage -l user在變量中output，需要檢查用戶帳戶密碼是否未過期或將在 90 天內過期。import reoutput = '''Last password change : Aug 26, 2017Password expires : neverPassword inactive : neverAccount expires : neverMinimum number of days between password change : 0Maximum number of days between password change : 99999Number of days of warning before password expires : 7'''regexp = re.compile(r'Password expires [ ]*(:*?)')match = regexp.match(output)if match: VALUE = match.group(2)現在，我需要將值存儲在一個變量中以繼續(xù)前進但無法做到這一點。以上是我的代碼。理想情況下，VALUE 應該有“從不”。

re.match不會在整個字符串中查找模式，而是會在字符串的開頭匹配它（就像正則表達式以 開頭一樣^）。所以你需要re.search，它將檢查整個目標字符串的模式：
import re
output = '''Last password change : Aug 26, 2017
Password expires : never
Password inactive : never
Account expires : never
Minimum number of days between password change : 0
Maximum number of days between password change : 99999
Number of days of warning before password expires : 7
'''
regexp = re.compile(r'Password expires\s+: (.*)')
match = regexp.search(output)
if match:
VALUE = match.group(1)
print(VALUE)
