I want to plot in the csv file the symbol gamma in greek letter. I tried Unicode and the CSS code but I got errors or not the desired result.

For instance, the CSS-code for gamma is the following one:\03B3 

Home=[['home','\03B3 ']]

if glass_type!=3:
    with open('Output.csv', 'w', newline='') as csvFile:       

    thewriter.writerows(Home)

The expected result is the symbol Gamma in Greek letter; but, I get the following result: B3

Consider that the CSS code works for the degree symbol with the following code: \xb0

You're specifying the unicode CSS code wrong:

Home=[['home','\u03B3 ']] # note the \u

printing Home results in:

[['home', 'γ']]

Note, however, that since python 3's default strings are unicode, you could just use the gamma symbol in your script (this improves readability a lot too, btw):

Home = [['home', 'γ']]

  • Put the full error output (including the line and trace) in your question. Also, add the output of running `python --version` in a terminal window – GPhilo Jun 25 '19 at 08:28

  • What version of python are you using **exactly**? This is important, because versions prior to python 3.6 require you to install the package `win-unicode-console` (see [this answer](https://stackoverflow.com/a/32176732/3214872) for more details). You can get python's versions importing `sys` and printing `sys.version`, or by running in a console `python --version` – GPhilo Jun 25 '19 at 08:44
  • Actually, does `print('\u03B3')` raise any error? Or is the error coming from inside `writerows` (in which case I can't help you further without seeing the implementation of `writerows`)? – GPhilo Jun 25 '19 at 08:46
  • Hi, you are right. It works fine.The implementation in writerows are attached above – chrisis Jun 25 '19 at 08:49
