QUESTION
Note: This question is certainly different from Does re in Python support word boundaries (/b). The alluded link seeks an answer for a very simple query for which a cursory glance on any tutorial in Python regular expression would have provided the explanation with examples. My question was using a word boundary around an OR expression and is far from trivial or to be reckoned as duplicate.
I was trying to build a palatable example to demonstrate regex word boundaries. Towards this, I wanted to show how the singular food items ordered by a diet-conscious person are changed for a guzzler and wrote the following program:
...ANSWER
Answered 2019-Nov-10 at 09:47In order to satisfy the guzzlers you need to escape the \b
s or use the raw input format i.e.
QUESTION
I want to sort the data frame by the contents of column. On using sort() function but not getting a sorted data frame
I have a data frame with column like name, age, gender. I want to sort the data frame according to age
I tried sort(data_info$Age) which gave correct output :
...ANSWER
Answered 2019-Jul-07 at 22:11We need to use order
instead of sort
as sort
returns the sorted values, but it can also get the index if we use index.return = TRUE
. Then, it would return a list
with names 'x' and 'ix' for the sorted values and the corresponding index. By looking at the data, the column is factor
. We can convert it to numeric
and then order
to order the rows of the dataset
QUESTION
I had a task to do which I have accomplished almost but I have been stuck to a last part.
What I am doing
- I have JSON data from back end which I am calling at once then showing it as a HTML table but only
10
rows at a Time,If rows are more than 10 then it will show in two parts first 10 then after 5 seconds next 10, You can check my snippet for that - When it will be the last page of table, then what I am doing is showing an Image, If Image is one then table-->Image if there are more than one Image suppose 2 images there than table-->image1-->table-->image2 like this it is working
- When once the cycle is completed like table-->image then I am calling table function once again because it will have dynamic data
- Here the Image data is also coming in JSON and it is also dynamic there I am facing issue
Issue
- I have a function
imageFormatter()
which is having data for Image in JSON format - These Images are set in my database as column name
IsActive
so when I am calling this data I am checking for this condition in my db via query - Now my table is showing up on UI and iamges are also, but in my database that
IsActive
flag can be changed at any time fromY
toN
- Now what I am trying to do is I want the function
imageFormatter()
to get refreshed at every 5 seconds so that it can take the new data - To change that
IsActive
I have a UI which user is handeling on click of go whatever Image user selects I am saving it to db viaservlet
, now Just want to show call thisimageFormatter()
so that it can take newest Images
This is the approach I am using to do my task. Is there a better approach?
I have commented all the lines in my code for better understanding
...ANSWER
Answered 2019-Jun-14 at 10:43Try this. I have added the logic to reload when it is last image.
