Have you ever forgotten to reference to a variable in Interactive Shell?
ignored returns are referenced to _
> from requests import get
> get('http://example.com')
# Oh no, forgot to reference
> response = _
> response
<Response [200]>

You don't have to write hello world anymore
Just import it!
> import __hello__
Hello world!
Just import it!
> import __hello__
Hello world!
Have you tried this?
# -*- encoding: nocolon -*-
for item in items
with open('output.txt', 'r') as f
f.write(item)
# -*- encoding: nocolon -*-
for item in items
with open('output.txt', 'r') as f
f.write(item)
When you want count elements of a list or letters of string use this:
> from collections import Counter
> c = Counter(["a", "b", "c", "a", "a"])
> c["a"]
3
> c["b"]
1
> c["d"]
0
> from collections import Counter
> c = Counter(["a", "b", "c", "a", "a"])
> c["a"]
3
> c["b"]
1
> c["d"]
0
To find out from where module got imported use this:
>import os
>os.__file__
'/usr/lib/python3.5/os.py'
Note that __file__ is created in every python file automatically.
if you have main.py, it will give full path to file.
print("ran the code", __file__)
>import os
>os.__file__
'/usr/lib/python3.5/os.py'
Note that __file__ is created in every python file automatically.
if you have main.py, it will give full path to file.
print("ran the code", __file__)
Need Calendar? Import it!
import calendar
# monthly
print(calendar.moth(2018, 9))
# yearly
print(calendar.calendar(2018))
import calendar
# monthly
print(calendar.moth(2018, 9))
# yearly
print(calendar.calendar(2018))

To run python code without entering interactive shell for quick check or calculation, use -c flag
$ python -c "print(42**2)"
1764
$ python -c "print(42**2)"
1764
Python was once offered to be used for interactive web pages (insted of js) if and only if it adopted curly braces instead of indentations.
