QUESTION
The following codes check for Duplicates in CSV file where TO Column is “USD”. I need your help to figure out how do I compare the resulted duplicate value, if the duplicate value has same value like in the below case, Perl should not give any warning, if the value is same. Perl file name is Source, just change the directory and run it.
...ANSWER
Answered 2020-Aug-02 at 12:33Like @Håkon wrote it seems like all your duplicates are in fact the same rate so they should not be considered duplicates. However, it could be an idea to store the rate in a hash mapped to each from and to currency. That way you don't need to check for duplicates every iteration and can rely on the uniqueness of the hash.
It's great that you use proper CSV parsers but here's an example using a single hash to keep track of duplicates by just splitting by ,
since the data seems reliable.

QUESTION
use List::MoreUtils 'uniq';
print join ", ", sort uniq ("b", "a", "a");
...ANSWER
Answered 2020-May-04 at 05:45That code falls under the sort invocation of
sort SUBNAME LIST
...
If SUBNAME is specified, it gives the name of a subroutine that returns an integer less than, equal to, or greater than 0 , depending on how the elements of the list are to be ordered.
The uniq
in the first example is taken as a bareword that specifies the name of the sub to use for sorting and qw(b a a)
is the list to sort -- you aren't uniq
-ing the list (so to speak) but are using uniq
as a sorting function for that list.
The error message comes as a sorting function needs to return a number and uniq
returns strings.
You've discovered one way to make it work, and can also use the unary +

QUESTION
I am currently using Ubuntu 16.04 LTS.
The problem is when I open up a Terminal, I get this message.
...ANSWER
Answered 2020-Feb-26 at 01:07As pointed out by the other answer, the cause of the problem is this:
- installed pew
(cvpr_env) ubuntu@ubuntupc:~/Downloads/camconvs-master$ pip install pew
Here you installed pew
while you were inside a virtualenv
.
As mentioned in my comment, installing pew
installs a binary under one of the standard bin
folders, which is usually /usr/local/bin/
or /home//.local/bin
or /usr/bin
, depending on your Python/pip
installation permissions.
