I am writing a test console program-phonebook with Python. My IDE is JetBrains PyCharm. I have 5 functions - Search contact, Enter contact, Delete contact, All phones and Exit. My question is how can I make the program to save information in text file and when I compile it, the information will be saved in this text file ?
You could write the data to a csv file. https://docs.python.org/3/library/csv.html
This should help : https://docs.python.org/2/tutorial/inputoutput.html
I think for your case the easiest would be to write data to a python file as follows:
with open('PathToAFile/MyFile.py', 'w') as f:
f.write('contact_names =[' + contact_name1 + ',' + contact_name2... + ']\n')
This will make it extremely easy to load data later without having to parse (as in a csv).
In the example code i provide, im saving your contact names to a list called 'contact_names' in a python file named 'MyFile.py'. When you execute 'MyFile.py
you will have access to the 'contact_names' variable

I'm looking for a way/module to insert a string of text formatted by position and text size, into an already existing .otp file(OpenDocument Presentation Template/Libre&OpenOffice version of a .ppt file). Preferably through Python. I've tried googling but the only thing I find is about macros and I'm not sure if that will work the way I want it to.
As an example I'm looking for an end product like this, where the text is inserted through running a Python script.
I imagine the outline of the script to look something like:
import modules
file = 'cat.otp'
open file
some function for inserting formatted text(right size, text size etc) in otp file
you wrote .opt in text and in pseudo-code .otp, but extension should be .odp for a presentation file. otp is for a master. If you just want to add content this should work for both:
While there is a convenient lib for pptx: python-pptx I don't know one for OpenOffice-Files.
If you don't have to create from scratch but just edit something (and it sounds like that) you may unpack the file via zipfile, edit the content.xml and zip back the whole file structure to odp-file. If you take your demo-file and read the xml (use notepad++ with XML-Tools extension and pretty print function to de-linearize) it is quite self-explaining, you'll get an idea pretty fast.
Sorry if the question is not well formulated, will reformulated if necessary.
I have a file with an array that I filled with data from an online json db, I imported this array to another file to use its data.
#file1
response = urlopen(url1)
a=[]
data = json.loads(response.read())
for i in range(len(data)):
a.append(data[i]['name'])
i+=1
#file2
from file1 import a
'''do something with "a"'''
Does importing the array means I'm filling the array each time I call it in file2?
If that is the case, what can I do to just keep the data from the array without "building" it each time I call it?
If you saved a to a file, then read a -- you will not need to rebuild a -- you can just open it. For example, here's one way to open a text file and get the text from the file:
# set a variable to be the open file
OpenFile = open(file_path, "r")
# set a variable to be everything read from the file, then you can act on that variable
file_guts = OpenFile.read()
From the Python docs on the Modules section - link - you can read:
When you run a Python module with
python fibo.py <arguments>
the code in the module will be executed, just as if you imported it
This means that importing a module has the same behavior as running it as a regular Python script, unless you use the __name__ as mentioned right after this quotation.
Also, if you think about it, you are opening something, reading from it, and then doing some operations. How can you be sure that the content you are now reading from is the same as the one you had read the first time?
Can Excel interpret the URLs in my CSV as hyperlinks? If so, how?
You can actually do this and have Excel show a clickable link. Use this format in the CSV file:
=HYPERLINK("URL")
So the CSV would look like:
1,23.4,=HYPERLINK("http://www.google.com")
However, I'm trying to get some links with commas in them to work properly and it doesn't look like there's a way to escape them and still have Excel make the link clickable.
Does anyone know how?
With embedding the hyperlink function you need to watch the quotes. Below is an example of a CSV file created that lists an error and a link to view the documentation on the method that failed. (Bit esoteric but that's what I am working on)
"Details","Failing Method (click to view)"
"Method failed","=HYPERLINK(""http://some_url_with_documentation"",""Method_name"")"
I read all of these answers and some others but it still took a while to work it out in Excel 2014.
The result in the csv should look like this
"=HYPERLINK(""http://www.Google.com"",""Google"")"
Note: If you are trying to set this from MSSQL server then
'"=HYPERLINK(""http://www.' + baseurl + '.com"",""' + baseurl + '"")"' AS url
you can URL Encode your commas inside the URL so the URL is not split across multiple cells.
Just replace commas with %2c
http://www.xyz.com/file,comma.pdf
becomes
=hyperlink("http://www.xyz.com/file%2ccomma.pdf")
Yes, but it's not possible to link them automatically. CSV files are just text files - whatever opens and reads them is responsible for allowing you to click the link.
As to how Excel seems to handle CSV files - everything between commas is interpreted as if it already had been typed into the cell. Therefore, the CSV file containing ="http://google.com",=A1 will display as http://google.com,http://google.com in Excel. It's important to note, however, that hyperlinks in Excel are metadata, and not the result of anything in the actual cell (ie, a hyperlinked cell to Google still contains http://google.com not <a>http://google.com</a> or anything of that sort.)
Since that's the case, and all metadata is lost when converting to a CSV, it's impossible to tell Excel you wish for something to be hyperlinked merely by changing the cell value. Normally, Excel interprets your input when you hit 'Enter' and links URLs then, but since CSV data is not being entered, but rather already exists, this does not happen.
Your best bet is to write some sort of addon or macro to run when you open up a CSV which parses every cell and hyperlinks them if they match a URL format.
Use this format:
=HYPERLINK(""<URL>"";""<LABEL>"")
e.g.:
=HYPERLINK(""http://stackoverflow.com"";""I love stackoverflow!"")
P.S. The same format works in LibreOffice Calc as well.
"=HYPERLINK(\"\" " + "http://www.mywebsite.com"+ "\"\")"
use this format before writing to CSV.
As described above, "=HYPERLINK(""http://www.google.com"", ""Google"")" is what worked for me.
However, In Excel Version 2204 Click to Run, I couldn't have leading white space.
For example;
FirstName, "=HYPERLINK(""http://www.google.com"", ""Google"")" fails
FirstName,"=HYPERLINK(""http://www.google.com"", ""Google"")" success
The issue here for me was that because a .CSV by it's nature is Comma separated, any commas in the text file are interpreted as separators. It worked for me by using tab characters as separators, saving it as a .TXT file so that when opened in EXCEL you choose the TAB character rather than ','.
In the text file …
## ensure that the file is TAB separated
Item 1 A file Name data.txt
Item 2 Col 2 =HYPERLINK("http:\www.ilexuk.com","ILEX")
"ILEX" then is shown in the cell and "http:\www.ilexuk.com" is the hyperlink for the cell.
I'd like to automate a loop:
ABAQUS generates a Excel file;
Matlab utilises data in Excel file;
loop 1 and 2.
Now my question is: after step 1, the Excel file from ABAQUS is unsaved as Book1. I cannot use Matlab command to save it. Is there a way not to save this ''Book1'' file, but use the data in it? Or if I can find where it is so I can use the data inside? (I assume that Excel always saves the file even though user doesn't?)
Thank you!
As agentp mentioned, if you are running Abaqus via a Python script, you can just use Python to create a .txt file to save all the relevant information. If well structured, a .txt file can be as readable as an Excel spreadsheet. Because Matlab and Python have intrinsic functions to read and write files this communication can be easily done.
As for Matlab calling Abaqus, you can use something similar to:
system('abaqus cae nogui=YOUR_SCRIPT.py')
Your script that pipes to Excel should have some code similar to this:
abq_ExcelUtilities.excelUtilities.XYtoExcel(
xyDataNames='S:Mises PI: PART-1-1 E: 4309 IP: 1', trueName='')
writing the same data to a report (.rpt) file the code looks like this:
x0 = session.xyDataObjects['S:Mises PI: PART-1-1 E: 4309 IP: 1']
session.writeXYReport(fileName='abaqus.rpt', xyData=(x0, ))
now to "roll your own", use that x0 object: x0.data is a regular python tuple holding the actual data which you can write to a file however you like, eg:
file=open('myfile.csv','w')
for point in x0.data: file.write('%g,%g\n'%point)
file.close()
(you can comment or delete the writeXYReport call )
I'm almost an absolute beginner in Python, but I am asked to manage some difficult task. I have read many tutorials and found some very useful tips on this website, but I think that this question was not asked until now, or at least in the way I tried it in the search engine.
I have managed to write some url in a csv file. Now I would like to write a script able to open this file, to open the urls, and write their content in a dictionary. But I have failed : my script can print these addresses, but cannot process the file.
Interestingly, my script dit not send the same error message each time. Here the last : req.timeout = timeout
AttributeError: 'list' object has no attribute 'timeout'
So I think my script faces several problems :
1- is my method to open url the right one ?
2 - and what is wrong in the way I build the dictionnary ?
Here is my attempt below. Thanks in advance to those who would help me !
import csv
import urllib
dict = {}
test = csv.reader(open("read.csv","rb"))
for z in test:
sock = urllib.urlopen(z)
source = sock.read()
dict[z] = source
sock.close()
print dict
First thing, don't shadow built-ins. Rename your dictionary to something else as dict is used to create new dictionaries.
Secondly, the csv reader creates a list per line that would contain all the columns. Either reference the column explicitly by urllib.urlopen(z[0]) # First column in the line or open the file with a normal open() and iterate through it.
Apart from that, it works for me.
