The glob function will allow you to retrieve a list of files names that match a certain pattern. If you load that list into @ARGV, then you can process all the files–even in order with a single loop: use strict; use warnings; use Getopt::Long; sub usage ($) { my $msg = shift; die <<“END_MSG”; *** … Read more
In Python, evaluation is in reverse order. Therefore this: node = node.next = ListNode(10) is the same as this: node = ListNode(10) node.next = node So, you have to reverse order of elements before last assignment: node.next = node = ListNode(10) # same as: node.next = ListNode(10) node = node.next 4 solved how does python … Read more

You can use groupby and join to create the expected output. One way is to create a column to_join from the columns Tri_gram_sents and Value, and then agg this column: df[‘to_join’] = df[‘Tri_gram_sents’] + ‘ ‘ + df[‘Value’].astype(str) ser_output = df.groupby(‘sentence’)[‘to_join’].agg(‘ ‘.join) Or you can do everything in one line without create the column with … Read more

What you were doing before doesn’t work, and also only converts to uppercase 11 solved How to inverse string … Read more
Actually the code in question works on unix systems, but usually the problem is that calls like fmt.Scanf(“%f”, &x1) does not consume newlines, but quoting from package doc of fmt: Scanning: Scan, Fscan, Sscan treat newlines in the input as spaces. And on Windows the newline is not a single \n character but \r\n, so … Read more
First of all, if you are gonna retain more than one instance of the class then you are actually not using Singleton pattern (as pointed out by ANS).
