Trusted Python $3$ O Q Run Code Memory: $279/2048$ MB Question $3$c In question $3$a we noticed a large number of potentially invalid ZIP codes $($e$.$g$."$CA$").$ These are likely due to data entry errors. To get a better understanding of the potential errors in the zip codes we will: $1.$ Import a list of valid San Francisco ZIP codes by using pd$.$ read$\_$json to load the file data$/$st$\_$zipcodes.json and extract a series of type str containing the valid ZIP codes. Hint: set dtype when invoking read$\_$Json. $2.$ Construct a DataFrame containing only the businesses which DO NOT have valid ZIP codes. You will probably want to use the series.isin function, Step $1$ In $[45]$: valid$\_$zip $-$ pd$.$ read$\_$json$($dsDirl$\text{'}$sf$\_$zipcodes.json'.dtype$-$str$)$ valid zips$-$valid$\_$zipt"zip$\_$codes"$).$str$.$extract$(\text{'}\{\backslash$d$(5))\text{'},$ expand$-$False$)$ valid$\_$zips.head $(20)$ Out$[45]94102194103294104394105494107594108694109794110$ B $941119941121094114119411512941161394117149411815941191694120179412118941221994123$ Name: zip$\_$codes, dtyper object Control P Help $+$ N Run $$ Code In $[45]$: valid$\_$zip $-$ pd$.$ read $3$son$($dsDirl$\text{'}$sf$\_$zipcodes.json',dtype$=\{$tr$\})$ valid$\_$zips$-$valid$\_$zipl"zip$\_$codes"$).$str$.$extract$("(\backslash$d$(5))",$ expand$-$False$)$ valid$\_$zips.head $(20)$ Python Memory: $279/204$ Out $[45]$: $0941021941032941043941054941075941086941097941108941119941121094114119411512941161394117149411815941191694120179412118941221994123$ Name: zip codes, dtyper object In $[46]$: grader.check$("$q$3$ci$")$ Out$[46)$: All tests passed!
