What do you like best?
We like PDFfiller because our patients don't want to have to waste precious minutes of their appointment time completing a health history update in the office. It's much simpler, not to mention faster, to have them do it at home and submit it when they're done!
What do you dislike?
The log-in process for the patient who has never used this service. We have a few patients who value their privacy and would rather not have to create an account in order to complete a form.
What problems are you solving with the product? What benefits have you realized?
PDFfiller is wonderful for our new patients! We send them to our website and have them navigate to where we have the clickable button to either complete the forms online or to print and bring them with to their appointment.

Default At Company I like that I can read-only PDFs straight from Gmail - previewing with PDFfiller is way easier than having to download through Adobe. I feel like there is nowhere to go if you need assistance or a homepage to see all of the PDFs that you have viewed.

Takes a little getting used to, but not bad Fairly easy to use once you get used to the set up and lay out. I had used different software to begin with so it took some time to get used to. I like the fact that you can create or upload your document, fill it out, sign it and then send it off to be signed by another party all in one place. Took some getting used to as I had used different products in the past. Other than that, there really is nothing bad about this software.

Well Well, this is my first experience and it was very well, although I will be sure of this assestment until I receibe the opinion of my coleges since they will read the edited pdf. What I think that PdfFiller is doing well? Well let me have another edition experience and I will be on the condition to answer this question. The only thing that I didn't like, was that I select the option to pay 15 dlls and the charge to my credit card was almost twice.

This program/software is very user friendly. When I started my 30 day trial, I just couldn't believe how comfortable I felt using this program. I'm very happy with it. I am happy that I was invited to a webinar, this will help me master the program.

What do you like best? How easy it is to use, the signature function too. What do you dislike? History saves only one document and can't change it. Recommendations to others considering the product: It's great, so don't hesitate What problems are you solving with the product? What benefits have you realized? Don't need a printer and scanner to fill out documents

There are some glitches There are some glitches, like if you type to fast it will double or triple the word your typing. But other than that it's great.

To delete rows and columns from Databases, Pandas uses the drop function. To delete a column, or multiple columns, use the name of the column(s), and specify the axis as 1. Alternatively, as in the example below, the 'columns' parameter has been added in Pandas which cuts out the need for 'axis'.
Pandas' drop function can be used to drop multiple columns as well. To drop or remove multiple columns, one simply needs to give all the names of columns that we want to drop as a list. Here is an example with dropping three columns from gap minder data frame.
Deleting rows and columns (drop) To delete rows and columns from Databases, Pandas uses the drop function. To delete a column, or multiple columns, use the name of the column(s), and specify the axis as 1.
Delete a Multiple Rows by Index Position in Database As of. drop() function accepts only list of index label names only, so to delete the rows by position we need to create a list of index names from positions and then pass it to drop(). As default value of place is false, so contents of DOB will not be modified.
ALTER TABLE “table_name” DROP “column_name”; ALTER TABLE “table_name” DROP COLUMN “column_name”; ALTER TABLE Customer DROP Birth_Date; ALTER TABLE Customer DROP COLUMN Birth_Date; ALTER TABLE Customer DROP COLUMN Birth_Date;
To join these Databases, pandas provides multiple functions like conceit(), merge(), join(), etc. In this section, you will practice using merge() function of pandas. You can notice that the Databases are now merged into a single Database based on the common values present in the ID column of both the Databases.
Delete a Multiple Rows by Index Position in Database As of. drop() function accepts only list of index label names only, so to delete the rows by position we need to create a list of index names from positions and then pass it to drop(). As default value of place is false, so contents of DOB will not be modified.
Rows can also be removed using the drop function, by specifying axis=0. Drop() removes rows based on labels, rather than numeric indexing. To delete rows based on their numeric position / index, use IOC to reassign the data frame values, as in the examples below.
Drop Empty Rows or Columns If you're looking to drop rows (or columns) containing empty data, you're in luck: Pandas' drop() method is specifically for this. Technically you could run MyDataFrame. Dropna() without any parameters, and this would default to dropping all rows where are completely empty.
Python | Pandas Database.drop() Pandas drop() method allows the user to analyze and drop Rows/Columns with Null values in different ways. ... 'any' drops the row/column if ANY value is Null and 'all' drops only if ALL values are null.
