[Tutor] Using Python to solve factoria
Hello, I really happy to be accepted to the list! This is my current function: def factoria(numb): While numb > 1: If numb==0: return 1 Else: result = numb*(numb-1) numb = numb -1 return result factoria(5) #should output 120 What am I not getting right?

[Tutor] Fwd: Question about selenium with python
Hello,
Im a new programmer and this is my first time posting here. I have a
question about using selenium with python. My first question is how do I
get selenium to click on a link contained within a specific cell of a
table? I know how to get selenium to click on a link in general but in this
case there are several links which have the same name, but each of these
links are in a different cell. Basically Id like to give selenium the
location of a specific cell, and then tell it to click on the link inside
that cell.
Lets say the link is located in the 3nd row and 3nd column of a table. I
tried the following code but it didnt work
link = driver.find_element_by_xpath("//tr[3]/td[3]")
link.click()
Thanks
Fuzz
heres an example of the HTML code im working with:
Name
Clinic
#
Name1
MRN1
Plans

I'll help you part way. Firstly Python is case sensitive. You have several examples of where you start Python keywords with a capital letter when it should be lowercase. Secondly Python uses indentation (Conventionally 4 spaces.) to segregate code blocks. Thirdly, you won't see the result of your function if you don't print it. So if I correct these in your code I get: def factoria(numb): while numb > 1: if numb==0: return 1 else: result = numb*(numb-1) numb = numb -1 return result print(factoria(5)) But alas! There is more work to be done. This will not give you a syntax error, but now there is an issue with logic error(s). Can you figure it out? It might help if you pretend you are the computer and work out the while loop on paper through each iteration until it exits. Also, when you ask for help you should copy and paste the full traceback of the error you received. What did you get? Did the error relate to anything I corrected above? Unfortunately you won't get a traceback for logic errors! Also give the version of Python and your operating system. I am assuming you are using Python 3.

Python is written in C, so it only needs the C runtime, which is now an OS component. I provided a link for the updated download for the Universal C Runtime, KB3118401. The above Stack Overflow answer mentions KB2999226, which is the old, outdated update from well over a year ago. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
[Tutor] Open a libreoffice calc file in Python
Python 3.4 on Ubuntu If I was going to open a libreoffice calc file from the terminal I would go: libreoffice --calc /home/path/to/myfile.ods. How would I do this from Python?

My first thought was: import os os.system(insert_your_command) But looking at the documentation (https://docs.python.org/3/library/os.html#os.system) it says it is preferable to use the subprocess module with documentation here: https://docs.python.org/3/library/subprocess.html#replacing-os-system It makes me wonder if I should go back and revisit some code I wrote as I used the os.system()approach. But was this option available in Py 2.4.4?

But was this option available in Py 2.4.4? I'll have to check. Subprocess arrived with Python 2.4, so you should be fine. To my mind the more important thing is to use the "shell=False" version of Popen. os.system() inherently accepts a shell command string, which means you need to hand quote the /home/path/to/myfile.ods. But it is better to pass an array of strings: ['libreoffice', '--calc', path_value] where path_value is a Python variable containing "/home/path/to/myfile.ods" or whatever the path is. This way you don't need to do anything special for, um, "unusual" paths because you're not passing the string _through_ the shell. BTW, the array form is Popen's default mode; sensibly you need to _ask_ to use a shell string with shell=True, because that is harder and more fragile.

Without shell=True, args as a string on POSIX is generally an error
because it will look for the entire string as the executable. The
exception is if the string has no command-line arguments (e.g.
Popen('ls')).
On Windows it's always acceptable to pass args as a string. For a
complex command line it may be easier to pass args as a list and let
Popen call list2cmdline to create a string that's properly quoted and
escaped. Here 'properly' assumes the target executable parses its
command line using VC++ rules. It may use custom rules, in which case
you have to pass args as a string.
