How to extract key and value pairs using regular expressions in Python for given code?
问题
Sure, here's the translated code snippet with the corrected regular expression pattern:
import re
pattern = r'{% (\w+)\s*=\s*"(.*?)" %}'
text = '{% set name = "testDB" %}'
match = re.search(pattern, text)
if match:
key = match.group(1)
value = match.group(2)
print("key:", key)
print("value:", value)
else:
print("No match found.")
This code should correctly extract the key and value from the given text variable.

How can I parse this code with regular expressions in Python?
text1 = '{% set name = "testDB" %}'
text2 = '{% set version = "0.0.1" %}'
I need output as in form of key and value where I can store
key_text1 = set name and value_text1 = testDB.
Similarly for text2, key_text2 = set version and `value_text2 = 0.0.1
the code I tried is follow:
import re
pattern = r"^{% (\w+)\s*=\s*'(.*?)' %}$"
text = '{% set name = "testDB" %}'
match = re.search(pattern, text)
if match:
key = match.group(1)
value = match.group(2)
print("key:", key)
print("value:", value)
else:
print("No match found.")
and the output am getting here is No match found instead key and value

根据所显示的数据，看起来您想要从字符串中提取两个双引号之间的内容。如果是这样的话，以下是代码的翻译部分：
import re
text1 = '{% set name = "testDB" %}'
text2 = '{% set version = "0.0.1" %}'
pattern = re.compile(r'(?<=").*?(?=")')
for text in text1, text2:
print(pattern.findall(text))
输出：
['testDB']
['0.0.1']
英文:
Given the data shown, it appears that you want to isolate whatever's between two double-quotes in the string. If that's the case then:
import re
text1 = '{% set name = "testDB" %}'
text2 = '{% set version = "0.0.1" %}'
pattern = re.compile(r'(?<=").+?(?=")')
for text in text1, text2:
print(pattern.findall(text))
Output:
['testDB']
['0.0.1']
