Python Programming: Lesson 3 - Delimiters, Escape Sequences, and Strings смотреть онлайн

PLEASE SUBSCRIBE!!!

We've started our Python exploration with 3 videos - downloading PyCharm, printing statements (and comments), and arithmetic expressions:
Lesson 0: https://youtu.be/Y2DahH65XW0
Lesson 1: https://youtu.be/_NTGCET93Vw
Lesson 2: https://youtu.be/vyfi1Fmen4g

There are 2 types of delimiters to be familiar with
print( ' sup \'Nally\'') prints sup 'Nally'
print( "The \"book\"" ) prints The "book"

There are 2 types of escape sequences to be familiar with
print( " \n " ) prints a new blank line (in addition to going to the next one)
print( "\t" ) prints a new tab, 4 spaces

Use """, 3 pairs of double quotes, at the beginning and end of a string to make it a multi-line string that you can print.

To concatenate two strings, we can write "butter" + "fly" to get "butterfly". We can also write "co" * 2 to get "coco".

An equivalent lesson in Java is available here, but it is a more advanced lesson that also covers 2D arrays (second half of video requires prior knowledge): https://youtu.be/kPRuuht2stw
