QUESTION
There seem to be lots of similar questions, but I cannot find the answer I need. So hopefully someone is able to help me.
Here are my two dataframes:

I think you should rbind
the two datasets. For clarity you can then get the data in wide format so that you have only 1 row for each country.
QUESTION
I have to write a python program for the following problem
Write a complete and syntactically correct Python program to solve the following problem: Write a program for the local coffee shop owner who wants to be able to control his inventory. The program must be written in accordance with the following specs:
- Write the following data to an external file, name the file coffeeInventory.txt Description Pounds Blonde Roast 15 Medium Roast 21 Flavored Roast 10 Dark Roast 12 Costa Rica Tarrazu 18
- You do not need to write the table, just the data
- Read in the records you just wrote to coffeeInventory.txt and display them on the screen and sum the total pounds of coffee
- Append these records to the file Guatemala Antigua 22 House Blend 25 Decaf House Blend 16
- Modify the file by allowing the owner to remove data from the file: a. Ask the owner to enter a description to remove b. If the description exists, remove the coffee name and the quantityc. If the description is not found, display the message: That item was not found in the file.
- Modify the file by allowing the owner to delete data from the file: a. Ask the owner to enter a description to delete b. If the description exists, delete the coffee name and the quantity c. Replace the name and quantity of the coffee removed in step b by asking the user to enter a new coffee name and quantity d. If the description is not found, display the message: That item was not found in the file.
this is what I have so far

df <- data.frame(Country = c("Indonesia","Indonesia","Brazil","Colombia","Mexico","Colombia","Costa Rica" ,"Mexico","Brazil","Costa Rica"),
Subject = c("Boys", "Girls","Boys","Boys","Boys","Girls","Boys","Girls","Girls","Girls"),
Value = c(358.000,383.000,400.000,407.000,415.000,417.000,419.000,426.000,426.000,434.000))
...ANSWER
Answered 2021-Mar-30 at 17:11Arranging your data frame does not change the way the column Country
will be ordered on the x axis. The priority for the order on the axis for discrete variables is:
- If you supply a
reorder
or final specification inaes()
, use that ordering - If the column is a factor, use the order of the
levels
of that factor - If the column is not a factor, order alphanumerically
As far as I know, you can only specify one column to use in reorder()
, so the next step is to convert to a factor and specify the levels
. The way the items appear in the ordering of the data frame does not matter, since the columns are treated completely separate from the order in which they appear in the data frame. In fact, this is kind of the whole idea behind mapping.
Therefore, if you want this particular order, you'll have to convert the Country
column into a factor and specify levels
. You can do that separately, or pipe it all together using mutate()
. Just note that we have to specify to use unique()
values of the Country
column to ensure we only provide each level one time in the order in which they appear in the sorted data frame.
QUESTION
This thread explains the nature of nsmap
in an lxml.etree
.
Given the following XML and parsing code, I try ElementTree.dump
and etree.dump
to view. The display from ET shows various namespaces ns1
, ns2
, etc. Does this mean the ET actually generate internal namespace? if so, can we or how do we use it, for example, to search for an element whose name we know, but not its URI?
my_xml.xml
ANSWER
Answered 2021-May-12 at 19:14ElementTree (ET) and lxml differ in the way they handle namespaces
ET generally does not preserve the namespace prefixes defined in an input document and does not store whether a namespace was a default namespace. ET also moves all namespace declarations to the outermost element.
lxml generally preserves prefixes and default namespaces.
For instance, if your input document is:
QUESTION
I have an XML with many levels. Each level may have namespace attached to it. I want to find
a specific element whose name I know, but not its namespace. For example:
my_file.xml
ANSWER
Answered 2021-May-11 at 18:57You could declare all namespaces, but given the structure of your sample xml, I would argue you are better off disregarding namespaces altogether and just using local-name()
