notice the now familiar symbols there is | 4,235.48 | 5.32 |
the carrot symbol at the very top there | 4,238.44 | 5 |
is the dollar sign at the very end there | 4,240.8 | 4.64 |
is a square bracket over here and then | 4,243.44 | 3.84 |
some of these ranges plus other | 4,245.44 | 3.84 |
characters turns out you don't normally | 4,247.28 | 3.879 |
see these characters in email addresses | 4,249.28 | 3.399 |
it looks like you're swearing at someone | 4,251.159 | 3.601 |
in their username but they're valid | 4,252.679 | 4.081 |
characters they're valid officially that | 4,254.76 | 3.479 |
doesn't mean that Gmail is going to | 4,256.76 | 4 |
allow you to put dollar signs and other | 4,258.239 | 4.241 |
punctuation in your username but | 4,260.76 | 4.08 |
officially some servers might allow that | 4,262.48 | 4.36 |
so if you really want to validate a | 4,264.84 | 4.16 |
user's email address you would actually | 4,266.84 | 4.56 |
come up with or copy paste something | 4,269 | 5 |
like this but honestly this looks so | 4,271.4 | 4.4 |
cryptic and if you were to type it out | 4,274 | 3.96 |
manually you are so likely to make a | 4,275.8 | 4.399 |
mistake what's the better solution here | 4,277.96 | 5.239 |
instead this is where P past week's | 4,280.199 | 5.641 |
libraries are your friend sure someone | 4,283.199 | 5.121 |
else on the internet a programmer more | 4,285.84 | 4.839 |
experienced than you even has come up | 4,288.32 | 5.12 |
with code that validates email addresses | 4,290.679 | 4.681 |
properly using this regular expression | 4,293.44 | 3.52 |
or even something more sophisticated | 4,295.36 | 3.52 |
than that so generally if the problem at | 4,296.96 | 4.4 |
hand is to validate input that is pretty | 4,298.88 | 4.96 |
conventional an email address a URL | 4,301.36 | 3.839 |
something where there's an official | 4,303.84 | 3.799 |
definition that's independent of you | 4,305.199 | 5.241 |
yourself find a popular library that | 4,307.639 | 5.281 |
you're comfortable using and use it in | 4,310.44 | 4.56 |
your code to validate email addresses | 4,312.92 | 4.64 |
this is not a wheel necessarily that you | 4,315 | 4.719 |
yourself should invent we've used email | 4,317.56 | 4.2 |
addresses though to iteratively start | 4,319.719 | 4.081 |
from something simple too simple and | 4,321.76 | 3.919 |
build on top of that so you could | 4,323.8 | 3.399 |
certainly imagine using regular | 4,325.679 | 2.921 |
Expressions still to validate things | 4,327.199 | 3.52 |
that aren't email addresses but are data | 4,328.6 | 4.599 |
that are important to you so we at least | 4,330.719 | 4.721 |
now have these building blocks now | 4,333.199 | 3.801 |
besides the regular Expressions | 4,335.44 | 2.96 |
themselves it turns out there's other | 4,337 | 3.88 |
functions in Python's re library for | 4,338.4 | 4.36 |
regular Expressions among them is this | 4,340.88 | 3.68 |
function here re. match which is | 4,342.76 | 4.28 |
actually very similar to re. search | 4,344.56 | 4.24 |
except you don't have to specify the | 4,347.04 | 3.32 |
carrot symbol at the very beginning of | 4,348.8 | 3.28 |
your Rex if you want to match from the | 4,350.36 | 4.6 |
start of a string re. match by Design | 4,352.08 | 4.96 |
will automatically start matching from | 4,354.96 | 3.96 |
the start of the string for you similar | 4,357.04 | 4.28 |
in spirit is re. full match which does | 4,358.92 | 4.12 |
the same thing but not only matches at | 4,361.32 | 3.2 |
the start of the string but the end of | 4,363.04 | 3.32 |
the string so that you too don't need to | 4,364.52 | 4.24 |
type in the carrot symbol or the dollar | 4,366.36 | 4.64 |
sign as well but let's go ahead and | 4,368.76 | 4.32 |
transition back now to some actual code | 4,371 | 3.76 |
whereby we solve a different problem in | 4,373.08 | 3.88 |
spirit rather than just validate the | 4,374.76 | 4.04 |
user's input and make sure it looks the | 4,376.96 | 3.84 |
way we want let's just assume that the | 4,378.8 | 3.879 |
users are not going to type in data | 4,380.8 | 3.839 |
exactly as we want and so we're going to | 4,382.679 | 3.801 |
have to clean up their input this | 4,384.639 | 3.641 |
happens so often when you're using like | 4,386.48 | 4.28 |
a Google form or Office 365 form or | 4,388.28 | 4.72 |
anything else to collect user input no | 4,390.76 | 4.56 |
matter what your form question says your | 4,393 | 4.12 |
users are not necessarily going to | 4,395.32 | 3.48 |
follow those directions they might go | 4,397.12 | 3.079 |
ahead and type in something that's a | 4,398.8 | 3.32 |
little differently formatted than you | 4,400.199 | 3.921 |
might like now you could certainly go | 4,402.12 | 4.64 |
through the results and download a CSV | 4,404.12 | 4.36 |
or open the Google spreadsheet or | 4,406.76 | 3.76 |
equivalent in Excel and just clean up | 4,408.48 | 4.12 |
all the data manually but if you've got | 4,410.52 | 4.199 |
lots of submissions dozens hundreds | 4,412.6 | 4.76 |
thousands of rows in your data set doing | 4,414.719 | 4.48 |
things manually might not be very fun it | 4,417.36 | 3.56 |
might be much more effective to write | 4,419.199 | 4.52 |
code as in Python that can allow you to | 4,420.92 | 5.44 |
clean up that data and any future data | 4,423.719 | 5.841 |
as well so let me propose that we go | 4,426.36 | 5.359 |
ahead here and close validate dopy and | 4,429.56 | 3.88 |
let's go ahead and create a new program | 4,431.719 | 4.041 |
alog together called format. Pi the goal | 4,433.44 | 4.68 |
of which is to reformat the user's input | 4,435.76 | 4.64 |
in the format we expect I'm going to go | 4,438.12 | 5.28 |
ahead and run code of format. piy and | 4,440.4 | 4.759 |
let's suppose that the data we're going | 4,443.4 | 4.56 |
to reformat is the user's name so not | 4,445.159 | 5.04 |
