Out of curiosity I would like to see the assembly instructions that correspond to the code of a .py file. Are there any trustworthy solutions you can propose?
The dis module disassembles code objects (extracting those from functions, classes and objects with a __dict__ namespace).
This means you can use it to disassemble whole modules:
import dis
dis.dis(dis)
although this isn't nearly as interesting as you may think as most modules contain several functions and classes, leading to a lot of output.
I usually focus on smaller functions with specific aspects I am interested in; like what bytecode is generated for a chained comparison:
def f(x):
return 1 < x ** 2 < 100
dis.dis(f)
for example.

I want this same print statement to give me these variables in separate statements:
x = 22.4
y = 23.4
print(y,\n x)
but Python doesn't seem to think it's obvious.
I have tried the r/n and I have also tried printing out my variables with separate print statements, but that is not what I want.
print(f'{y} \n{x}')
This will go good

This link will explain how we use f- strings
I recommend you use:
print("{}\n{}".format(x,y))

I am quite new to using config parser and have just discovered that my INI file hasn't been used as expected. as you can see below it has been seeing every letter as an individual list but I want the list to be separated by the commas.
config = ConfigParser()
config.read('Airline Gates/JST.ini')
print(len(config['Airports']['YMML']))
Output > 79
.ini
[Airport]
YMML=[E11,E12,E13,E14,E15,E16,E17,E18,E19,E20,G41,G42,G43,G44,G45,G46,G47,G50,G51,G52]
I am very sorry for a poor explanation I am awful at explaining things but I will be happy to give you any more information. thanks!
Go through This video https://www.youtube.com/watch?v=jBwfq6UMxkY for better understanding of ConfigParser. For your current problem you can format the string value from ini file as per your need.
print(config['Airport']['YMML'].split(','))

My point is that python has some predefined variables that you may have not even set, but still was given a value when you start off the shell. Say you ran the following code:
print (a)
Without even having defined variable "a" beforehand, it returned 0. Wherease, if you tried printing:
print(var1)
Would return an error because var1 was not defined. I did a bit of testing and found out the same goes for every other single character in python, print any of them out on the console and you will get the same result of 0.
The question I'd like to ask is that why are these characters given their own value beforehand? And are there special names for these predefined variables such as these? If I could know the name of these special variables, I could read upon some documentations about them.
There are no predefined variables in python.
print(a)
will return NameError: name 'a' is not defined as long as a has not been defined earlier.

I have write this code to collect all data from twitter for cities like London. I have tried to write a code using python and it's give me this error on the line:
def process_or_store(tweet):
print(json.dumps(tweet)
What can I do to fix this?
Set a tabulator or spaces in front of this line (depends on what you used in the above lines), so it looks like:
def process_or_store(tweet):
print(json.dumps(tweet))
Remind, that python does not use {} to determine where a function starts and ends. A function must be in one indentation level instead.
You also forgot to close brackets at print().
Take the above definition, its syntax is correct.
Be aware of mixing up tabs and spaces (some editors manage this automatically, but if not, this can lead to errors that are not obvious)
Update:
def process_or_store(tweet):
print(json.dumps(tweet)
To be:
def process_or_store(tweet):
print(json.dumps(tweet))
and then delete your question

In Python,
import shutil, os
allows me to call os.environ, os.path.exists(folder), os.listdir(pool), shutil.rmtree(folder) and shutil.copyree(). It seems that I call any function, defined in those modules. Nevertheless, I cannot call ctime() once I have imported import time. I must import ctime explicitly, by
from time import ctime
Why is such inconsistency? I find it difficult to program in such unpredictability.
from time import ctime allows to call ctime() directly, without time.ctime() prefix. It is me, who was inconsistent comparing fully qualified names os.listdir() with ctime() alone.
