Valid characters in a python class name

Can a space be given in variable naming. I tried a python program but it's showing an error I have attached the screenshot of the same.
enter image description here
You can't give a space. It's violating the naming convention. What you can do, add underscore (_) between words. Here is the correction:
Gal_Gadot = "Gal Gadot"
print(Gal_Gadot);
Hope this makes sense.

python - name of np array variable as string
(2 answers)
Closed 9 months ago.
If I wish to get the name of a numpy.ndarray converted to a string (but not the content of the numpy.ndarray, just the name only), how do I do that?
I tried str(npndarrayName) and npndarrayName.tostring() but both are converting the content and not the name itself only.
I am not sure if I fully understood what you're asking, but you can check this link because I think they had the same question as you.
I hope that it will solve your problem.

How to left align a fixed width string?
(8 answers)
Closed 1 year ago.
I was following a tutorial and found this.
print(f"{self.name}: {card!r:<3} ", end="")
And I have no idea what the !r:<3 means. Google wouldn't give me relevant results because of all the symbols.
You can find a description of the format of f-strings here and of the formatting language here.
!r:<3 uses repr to format the value, left aligned with a minimum width of 3 (padded with spaces by default).

Is it possible to unpack a tuple in Python without creating unwanted variables?

In Python it is good practice to use a single underscore for intentionally unused variables:
first_word, _ = 'only only is important'.split(' ', 1)
On the other hand, gettext uses the underscore as a short alias for its translation function, leading to clashes if the underscore is used for a variable before:
print(_('gettext will try to translate this string.'))
Question: What is the convention for the name of throwaway variables if gettext is used in the same namespace?

How to get only the last part of a path in Python?

Is it possible to manipulate a variable, for example:
file = "/Python/work.txt"
to just list work.txt, without /Python? excluding everything on the left of the "/"?
Thank you
Of course! Simply do this:
file = "/Python/work.txt"
excluded = file.split("/")[-1]
This would return "work.txt" in the excluded variable.

Add 'decimal-mark' thousands separators to a number
(9 answers)
Closed 8 years ago.
I am simply trying to execute the following command in Python:
print("Number is", format(49000.12345,"10.2f"))
So I would like it to print out like 49,000.12 for the number.
My teacher taught us to put a comma in "10.2f" like ",10.2f" for the thousands separator but it's not working. Could someone please tell me the correct simple way similar to that?
Thank you
See this: http://www.python.org/dev/peps/pep-0378/ It is the PEP introducing the ability into Python 2.7, 3.1 and later versions.
