填写代码,检查所传递的文本是否包含可能的美国邮政编码,格式如下:恰好是5位数字,有时,但不总是,后面还有4位数字的破折号。邮政编码前面至少要有一个空格,而且不能在文本的开头。
无法产生所需的输出。
import re
def check_zip_code (text):
result = re.search(r"\w+\d{5}-?(\d{4})?", text)
return result != None
print(check_zip_code("The zip codes for New York are 10001 thru 11104.")) # True
print(check_zip_code("90210 is a TV show")) # False
print(check_zip_code("Their address is: 123 Main Street, Anytown, AZ 85258-0001.")) # True
print(check_zip_code("The Parliament of Canada is at 111 Wellington St, Ottawa, ON K1A0A9.")) # False
您可以使用
(?!\A)\b\d{5}(?:-\d{4})?\b
完整的代码。
import re
def check_zip_code (text):
m = re.search(r'(?!\A)\b\d{5}(?:-\d{4})?\b', text)
return True if m else False
print(check_zip_code("The zip codes for New York are 10001 thru 11104.")) # True
print(check_zip_code("90210 is a TV show")) # False
print(check_zip_code("Their address is: 123 Main Street, Anytown, AZ 85258-0001.")) # True
print(check_zip_code("The Parliament of Canada is at 111 Wellington St, Ottawa, ON K1A0A9.")) # False
zipcodes
可能会有更多的帮助, import re
def check_zip_code (text):
return bool(re.search(r" (\b\d{5}(?!-)\b)| (\b\d{5}-\d{4}\b)", text))
assert check_zip_code("The zip codes for New York are 10001 thru 11104.") is True
