Blocks are used to contain code for many purposes. In Python, blocks are indicated with indention. Blocks do not define scope in Python.
- [Instructor] Python differs from many languages in how…blocks are delimited.…Python does not use brackets or any special characters…for blocks, instead it uses indentation.…Here in Komodo I've opened a working copy of blocks.py…from chapter two of the exercise files.…And you'll notice that down here on line seven,…we have a conditional statement,…if x is less than y,…and indented below that is this print statement.…So that indent means that it's a block and it's…associated with the control above it,…in this case the if statement.…
And so if I save and run this, you'll see that we get…that result from the print and if I put another print…down here,…and save and run, you see we get both of them.…But if the condition is not true,…if I change that condition to if x is greater than y,…and save and run,…you see now we only get the something else.…And I can put several other lines of code in here.…
And save and run and none of those are printed unless…the condition is found to be true.…And if I save and run, now we get all of that.…
