  2. Aims • Writing Python program • Creating files • Comments • Layout • Using ‘print’

  3. Python Program • Python programs can be very simple • File (best to name it with extension .py) • Much simpler than Java (or C♯) print(”hello”)

  4. Comments • Comment explain a program • Comments can be used to help plan a program # Thisprogram prints a greeting print(”hello”)

  5. Layout • An important feature of Python • Indentation matters! Always start in the same column

  6. The ‘print’ function • The ‘print’ function is used to output a string • In these examples • The print function has two strings or an expression • Note the spaces • Both statements output the same thing print(“hello“, “world“) print(“hello“ + “ hello“)

  7. Printing Numbers • Print can also output a number • Example >>> print("Average is", (30 + 40)/2) Average is 35.0

  8. Summary • A Python program is a file containing statements • Simple! • ‘print’ for output • String and numbers
