Python的lgb原則，即“Let’s Get Better”，是Python語言中推崇的一種最佳實踐。它強調代碼可讀性、易維護性和可擴展性，以提高Python程序的質量和效率。

為了遵循Python的lgb原則，我們可以在編寫Python程序時采取以下幾種方法：

import pandas as pd
import numpy as np
df = pd.DataFrame(data=np.random.randint(0, 10, (10, 5)),
columns=['a', 'b', 'c', 'd', 'e'])
# Avoid using single-letter variable names
# Use descriptive variable names instead
df.rename(columns={'a': 'age', 'b': 'gender', 'c': 'income',
'd': 'location', 'e': 'occupation'}, inplace=True)
# Use whitespace to improve code readability
# Add whitespace around binary operators and after commas
df['income'] = df['income'] / 1000.0
df.loc[df['gender'] == 0, 'gender'] = 'male'
df.loc[df['gender'] == 1, 'gender'] = 'female'
# Use comments to document your code
# Add comments to explain code logic or algorithmic approach
def compute_median(lst):
"""
Compute the median of a list of numbers
Args:
lst (list): List of numbers
Returns:
float: The median of the list
"""
lst.sort()
n = len(lst)
if n % 2 == 0:
return (lst[(n // 2) - 1] + lst[(n // 2)]) / 2.0
else:
return lst[(n // 2)]
# Use assert statements to check your code logic
# Add assert statements to verify code output
assert compute_median([1, 2, 3, 4, 5]) == 3
assert compute_median([1, 2, 3, 4]) == 2.5

通過遵循Python的lgb原則，我們可以編寫更易于閱讀、維護和擴展的Python代碼。這也有助于提高我們的編碼效率和代碼質量，讓我們在Python編程的道路上走得更遠。
