Variable names

Giving good names to your data.

Name your variables clearly

You can choose almost any name for a variable, but some rules apply. Names can contain letters, numbers, and underscores. They cannot start with a number. They cannot contain spaces.

PythonValid variable names.

sample_name = "Control"
temperature_1 = 30
_private = "hidden"

→

PythonNames cannot start with a number.

# This would cause an error:
# 1st_sample = "A"

→

Try it

Use descriptive names. sample_name is better than s. temperature_celsius is better than t. Your code will be easier to read later.
