import — Intermediate Examples

Loads a module or package into the current namespace

Import patterns and aliasing

Different ways to import and organize imports.

python

# Import specific items
from math import pi, sqrt, ceil

# Import with alias
import datetime as dt
now = dt.datetime.now()
print(f"Now: {now}")

# Conditional imports
try:
    import ujson as json
except ImportError:
    import json

data = json.dumps({"key": "value"})
print(data)

# Import in function scope (lazy loading)
def heavy_computation():
    import statistics
    return statistics.mean([1, 2, 3, 4, 5])

print(heavy_computation())

Use aliases for long module names. Conditional imports provide fallbacks. Function-scope imports delay loading until needed.
