Python From a White Sheet

ブリーフィング

Most beginner courses show you working code and ask you to admire it. This one plants the bug and lets it fire. You will write one program across four modules. It starts as a single `print` line and finishes as something that asks a question, cleans up whatever the person typed, decides what to do with it, does arithmetic on it, rejects nonsense and loops until it is satisfied. Every failure you meet on the way is one a real student hit first: the trailing space, the capital letter, the missing colon, the result you forgot to store, the number that was secretly a piece of text. By the end you will not have memorised Python. You will be able to find out why something does not work, which is the actual job.

1. 01 First Contact

   Nothing here is conceptual. You type, you run, you read what the computer says back. The only skill being trained in this module is reading an error message instead of panicking at it.

2. 02 Functions and Decisions

   3個のレッスン·1h 27m

   Two rules arrive in this module and they hold for the rest of your life in Python. All definitions above, all calls at the bottom. And indentation is imaginary brackets — the computer decides what…

3. 03 Cleaning What People Type

   3個のレッスン·1h 8m

   Dirty dishes go in the sink before the cupboard. Nothing a person typed goes into your logic until it has been through clean().

4. 04 Numbers, Validation and Loops

   3個のレッスン·1h 55m

   Garbage in, garbage out. input() always hands you text, even when it looks like a number, and the program that trusts it is the program that crashes in front of someone.
