I want to get a sentence that has both words and numeric characters. I tried many sources but still stuck.
My code:
eg_str= ['add - James Smith, Flat 7 118 Black-horse, MA-021-30', 'add - Alice, Derrick Street']
reg = re.findall(r'([a-z]{3,}[\s][-][\s][A-Z 0-9 a-z ,\-] )', str(eg_str))
print(reg)
Output I get:
['add - James Smith, Flat 7 118 Black-horse, MA-021-30', 'add - Alice, Derrick Street']
Expected output:
['add - James Smith, Flat 7 118 Black-horse, MA-021-30']
Can anyone help me what I'm missing here?
Update: Example pattern : 'add - James Smith, Flat 7 118 Black-horse, MA-021-30 - 1234'. I want to get exactly this pattern from the list of inputs I have. The regex should omit "ad - Alice, Derrick Street" and "add - Alice, Derrick Street - 1314". Is there a possibility to group expression to match the pattern as follows,
- 3 or more letters #add
- - # -
- Sentence with alphabets and numbers including, - #James Smith, Flat 7 118 Black-horse, MA-021-30
- - # -
- 4 or more digits #1234

You may match on the regex pattern:
[A-Z].*[0-9]|[0-9].*[A-Z]
Python script:
eg_str = ['add - James Smith, Flat 7 118 Black-horse, MA-021-30', 'add - Alice, Derrick Street']
matches = [x for x in eg_str if re.search(r'[A-Z].*[0-9]|[0-9].*[A-Z]', x, flags=re.I)]
print(matches) # ['add - James Smith, Flat 7 118 Black-horse, MA-021-30']

It looks like you could just access the first item in the list to get the answer you want.
print(eg_str[0])
If you are trying to apply the regex to each item in the list then you should loop through the list and then apply the correct regex to it.
eg_str= ['add - James Smith, Flat 7 118 Black-horse, MA-021-30', 'add - Alice, Derrick Street']
temp = []
for item in eg_str:
reg = re.findall(r'([A-Z].*[0-9]|[0-9].*[A-Z])', item)
temp.append(reg)
print(temp)
This would return:
[['James Smith, Flat 7 118 Black-horse, MA-021-30'], []]
