Practical Data Wrangling

Creating a regular expression to match the street address

Recall that in the street address, you are looking for the following pattern:

<street number> <initial street name> <street suffix>

The first part of the pattern string should match the street number. The street number is a sequence of digits located at the beginning of the string. For the sake of this exercise, I will ignore street addresses that contain letters (such as 10A or 10B) or ranges (such as 110-120). The following should be sufficient to capture the street address:

• A ^ symbol to indicate the beginning of the string
• A [0-9] range to indicate the range of all digits
• A + symbol following the digit range to indicate an indefinitely long sequence of digits
• A \s+ symbol to indicate ...
