I like tuples alot. But in some situations you seem to be forced to
access the elements of a tuple via its indexes and that is pretty
ugly. For example:
# make_color() returns a rgb tuple (r, g, b). I.e. (255, 0, 0)
print "The red value is: ", make_color()
Not nice at all. It is maybe OK for a rgb tuple that only has three
elements, but for a tuple that has 10+ elements, index access is
rediculous. In that case, unpacking wont helpe...

Tuples are defined with regards to parentheses ()'s as everyone knows.
This causes confusion for 1 item tuples since (5) can be interpreted
as a tuple OR as the number 5 in a mathematical expression
such as x = (5) * (4+6).
Wouldn't it have been better to define tuples with <>'s or {}'s or
something else to avoid this confusion??
Perhaps ()'s are a good idea for some other reason I don't know?

I have three tuples of the same size: tup1, tup2, tup3
I'd like to do something like this:
for a,b,c in tup1, tup2, tup3:
print a
print b
print c
Of course, you get an error when you try to run the pseudocode above.

I'm trying to understand the use of tuples in function argument lists.
I did this:
>>> def tester(a, (b,c)):
.... print a, b, c
....
>>> tester(1, 2)
Traceback (most recent call last):
File "<stdin>", line 1, in ?

I made a script that extracts strings from a binary file. It works.
My next problem is sorting those strings.

Please help me think of an example where immutable tuples are
essential.
It seems that everywhere a tuple is used one could just as easily use
a list instead.

Hi Pythonistas!
I've got a question about storing tuples in a dictionary. First, a
small test case which creates a list of dictionaries:
import time
list_of_dicts =
keys =
prev_clk = time.clock()

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...
