What is Python coding?

Writing plain-English instructions that a machine carries out in front of your eyes.

Python coding is everyday English written strictly enough for a computer to perform. Change any terracotta word below and press Run – no setup, no account.

pieces = ["cobalt", "amber", "coral", "cobalt", "jade"]
kept = []
for item in pieces:
    if item == "cobalt":
        kept.append(item)
print(kept)

Runs in browser · No sign-up

Exercise: Try changing "cobalt" to "jade" and press Run.

Hint

The word in quotes after == decides which pieces stay in the tray.

Solution

pieces = ["cobalt", "amber", "coral", "cobalt", "jade"]
kept = []
for item in pieces:
    if item == "jade":
        kept.append(item)
print(kept)

sky = "dusk"
weather = "clear"
welcome = "Start from zero"

for bay in range(1, 6):
    light_bay(bay)

Exercise: Light all eight bays and change the weather to rain.

Hint

range(1, 6) stops just before 6. Which end number reaches bay 8? Words like "rain" and "night" are allowed too.

Solution

sky = "dusk"
weather = "rain"
welcome = "Start from zero"

for bay in range(1, 9):
    light_bay(bay)

kept

A stone colonnade of eight bays at dusk with glass lanterns over a dark water channel
