One alternative is to send the file name as a parameter and write to the output file inside your script instead:

You may use this sed:

This awk does the job:

C++ Copy Constructors: must I spell out all member variables in the initializer list?

Yes, if you write a user defined copy constructor, then you must write an initialiser for every sub object - unless you wish to default initialise them, in which case you don't need any initialiser - or if you can use a default member initialiser.

the object contains some member variables which are pointers to its other member variables)

This is a design that should be avoided when possible. Not only does this force you to define custom copy and move assignment operators and constructors, but it is often unnecessarily inefficient.

But, in case that is necessary for some reason - or custom special member functions are needed for any other reason - you can achieve clean code by combining the normally copying parts into a separate dummy class. That way the the user defined constructor has only one sub object to initialise.

Like this:

You are using VQE the old way (when it was in Aqua), so it doesn't work anymore. What you should do instead is this :

EDIT: As replies have pointed out, you're likely attempting to check if your strings are in the line. This is also a valid approach, I've edited the code block to do this. (My original answer is also below.)

In Python, string.strip() will remove leading and trailing whitespace, not return the first or last word (as you're using it). You also need to use output.close() and call .readlines() on infile to turn it into an array of lines.

Delete from the existing dict (mutate original in-place)

Seaborn doesn't return this type of data. But the hexplot works similar to plt.hexbin. Both create a PolyCollection from which you can extract the values and the centers.

Here is an example of how the data can be extracted (and displayed):

An Amstrong number is a number where the sum of cubes of the digits are equal to the number.

If your input is taken as a string, you can iterate over the digits since strings are iterable in python:
