Lijst opsplitsen

fam

['liz', 1.73, 'emma', 1.68, 'mom', 1.71, 'dad', 1.89]

fam[3:5]

[1.68, 'mom']

fam[1:4]

[1.73, 'emma', 1.68]

![De syntaxis voor het opsplitsen van Python-lijsten, waarbij je ziet dat de startwaarde wel meetelt in de subset, maar de eindwaarde niet. (https://assets.datacamp.com/production/repositories/288/datasets/83dd2f807be0d4d08a187935eed11667c18fcfe3/slicing-syntax.png = 40)

fam

['liz', 1.73, 'emma', 1.68, 'mom', 1.71, 'dad', 1.89]

fam[:4]

['liz', 1.73, 'emma', 1.68]

fam[5:]

[1.71, 'dad', 1.89]
