Basic Mathematical Expressions

• Usage of +, -, *, /, %, //, and ** operators, beware of division by zero.
• Using simple mathematical expressions in assignment statements and functions.
• Operator precedence and the use of parenthesis.

Text IO

• Using string literals (character sequences or simply text) to output text on the console.
• Escaping special characters with backslash (\) to use in strings
• Using forward slash (/), without any trailing space to divide the source code into multiple lines.
• Using \n, the new-line character inside strings
• using end and sep arguments of the print() function.
• Passing multiple arguments to the print() function.
• Receiving user input() from the terminal and assigning the value to a variable.
• Replicating a string by * operator. Concatenating strings using the + operator.
• Using int() and float() functions to convert, a string to numerical form, i.e. type casting.
• Using open() function to read() from and write() to a file in the computer, with different access modes.
• Using try-except for runtime error handling.

Drawing with Input

• Drawing circles with turtle based on user input.
• Additional exercises to practice.
