My notes in learning python via sololearn.com

In except blocks, the raise statement can be used without arguments to re-raise whatever exception occurred.

try:
   num = 5 / 0
except:
   print('An error occurred')
   raise

The assert can take a second argument that is passed to the AssertionError raised if the assertion fails.

My notes in learning css via sololearn.com

Inline css styles should be placed in <head>

font-family

The font-family property specifies the font for an element. There are two types of font family names:

  • font family: a specific font family (like Times New Roman or Arial)
  • generic family: a group of font families with a similar look (like Serif or Monospace)

Separate each value with a comma to indicate that they are alternatives.

If the name of a font family is more than one word, it must be in quotation marks: "Times New Roman".
