Lecture 7- sep-18

learned subjects:

1. continue keyword in loops:
   • same as break, but only to exit the current iteration and continue stay in the loop.
2. basic algorithm of the maximum and minimum numbers.
3. None-type:
   • The None keyword is used to define a null value, or no value at all.
   • None is not the same as 0, False, or an empty string. None is a data type of its own (NoneType) and only None can be None.
   • shortcut conditions:

     max_n=None;
     ...
     if max_n is None or num>max_n:
          max_n=num
     

   • instead max_num==0 you can write: max_n is None

Extra:

• colors in console- build-in:

  • colors of tables references:

  • in the print() , you can style the output with text color, bold/bold intensity,underline ,background colors

  • examples:

  print("\033[1;92mBINGO\033[0m")  ## in BOLD with intensity in color green
  print(f"you guessed the number in \033[1;33m{tries}\033[0m tries") ## on the value of {tries} in yellow color
   print(f"\033[4;31mStatistical results:\033[0m") #text and underline in red
