使用正則表達式拆分查詢

Question

#我正在使用正則表達式來拆分它，但我得到了錯誤的結果。

import re

queries ="""
INSERT ignore into persons VALUES (15,'Tom D.', 'Erilchsen', 
'Skagen 21', 'Erlangen');
select * from persons;
"""

regex = "[;!]+?"
y = re.split(regex ,queries)
print(y)
print(len(y))
print(y[0])

output：

["\nINSERT ignore into persons VALUES (15,'Tom D.', 'Erilchsen', \n'Skagen 21', 'Erlangen')", '\nselect * from persons', '\n']

Answer 1

您實際上不需要正則表達式：

queries ="""
INSERT ignore into persons VALUES (15,'Tom D.', 'Erilchsen', 
'Skagen 21', 'Erlangen');
select * from persons;
"""

y = list(filter(None, queries.replace("\n", "").split(";")))
print(y)
print(len(y))
print(y[0])
