Have a set of string as follows
text:u\'MUC-EC-099_SC-Memory-01_TC-25\'
text:u\'MUC-EC-099_SC-Memory-01_TC-26\'
text:u\'MUC-EC-099_SC-Memory-01_TC-27\'
Use re.findall:
>>> import re
>>> strs = """text:u'MUC-EC-099_SC-Memory-01_TC-25'
text:u'MUC-EC-099_SC-Memory-01_TC-26'
text:u'MUC-EC-099_SC-Memory-01_TC-27'"""
>>> re.findall(r"'(.*?)'", strs, re.DOTALL)
['MUC-EC-099_SC-Memory-01_TC-25',
'MUC-EC-099_SC-Memory-01_TC-26',
'MUC-EC-099_SC-Memory-01_TC-27'
]
