Important changes from Java

  • When you pass an object to a function, and "reassign" it using its local function argument name, the outside objects won't get reassigned. This is because Python reassigns the local name only. This is a important difference from Java.

  • To iterate over two lists at the same time, use the zip built-in function:
for a,b in zip(list1, list2):

Casts

  • To cast a float to an integer, you can use the built-in int() function.
