db.insert({'name': 'Alice', 'age': 30})
db.insert({'name': 'Bob', 'age': 25})
User = Query()
result = db.search(User.name == 'Alice')
print(result)
11. Unidecode - Transliterate Unicode to ASCII
Unidecode comes to the rescue when you need to transliterate Unicode text into ASCII characters. It simplifies text normalization and handling non-ASCII characters.
Example:
from unidecode import unidecode
text = "Tōkyō"
ascii_text = unidecode(text)
print(ascii_text)
Tablib simplifies the handling of tabular data formats like Excel, CSV, and JSON. It's a versatile library that can save you time when dealing with diverse data sources.
Example:
import tablib
data = tablib.Dataset()
data.headers = ['Name', 'Age']
data.append(['Alice', 28])
data.append(['Bob', 35])
with open('data.xlsx', 'wb') as f:
f.write(data.export('xlsx'))
13. psutil - System Monitoring and Management
Psutil provides a wealth of information about system utilization, allowing you to monitor processes and manage system resources efficiently.
