Step 1: Basic Syntax and Data Types
1.1. Comments
- Lines beginning with a hash symbol (
#) are interpreted as comments. - Comment lines do not affect the execution of the program but are used to explain how the program works.
- Everything from the hash symbol to the end of the line is considered a comment.
Style Guide
- After the
#, add 1 space before beginning your comment text. - When adding a comment after a code statement, include at least 2 spaces between the code and the comment.
1.2. Screen Output
- To display data on the screen, use the
printfunction. - Strings are enclosed in double quotes (
") or single quotes (').
- By default, the print function inserts a newline at the end.
- If you don’t want to include a newline, specify an empty string (
'') for theendparameter.
📚 Exercise
Output the string “Hello, World!” in a single line by using two print statements - one for “Hello,” and one for " World!".
