从字符串更改 int 和 string

Question

The format_address function separates out parts of the address string into new strings: house_number and street_name , and returns: "house number X on street named Y" .

输入字符串的格式是：数字门牌号，后面是街道名称，它可能包含数字，但从不单独使用，并且可能有几个单词长。例如， "123 Main Street" 、 "1001 1st Ave" 或 "55 North Center Drive" 。

填补空白以完成此功能。

 def format_address(address_string):
  # Declare variables
  house_number=' '
  street_name=" "

  # Separate the address string into parts
  x=address_string.split(" ")
  # Traverse through the address parts
  for y in x:
    if(y.isdigit()):
      house_number=y
    else:
      street_name+=y
      street_name+=' '
    # Determine if the address part is the
    # house number or part of the street name
 # Does anything else need to be done
  # before returning the result?

  # Return the formatted string
    return "house number {} on street named {}".format(house_number,street_name)

print(format_address("123 Main Street"))
# Should print: "house number 123 on street named Main Street"

但它显示输出为：

 house number 123 on street named
house number 1001 on street named
house number 55 on street named

Answer 1

当您使用 str.split() 时，您可以选择要将字符串拆分成多少段 （只要不超过最大值） 。在您的情况下，该字符串应该只拆分一次，以将门牌号与街道名称分开。此外，您可以格式化字符串：

 def format_address(address_string):
    num, st = address_string.split(' ',1)
    return f"house number {num} on street named {st}"

print(format_address("123 Main Street"))

输出：

 house number 123 on street named Main Street
