python中不區分大小寫的CSV查詢

Question

我有弗吉尼亞道路上動物碰撞的數據集。 我正在嘗試提取涉及熊的所有碰撞。 在我的數據集中，使用至少三種不同的大小寫組合（即Bear，bear，BEAR）鍵入bear。 以下是我用來提取熊碰撞的代碼：

import csv

with open('google.csv', 'r') as f:
    reader = csv.reader(f)
    lines = [ row for row in reader if "bear" in row[4] ]

with open('outfile.csv', "w") as outfile:
    writer = csv.writer(outfile)
    writer.writerows(lines)

我該如何區分大小寫？

Answer 1

嘗試這個：

import csv

with open('google.csv', 'r') as f:
    reader = csv.reader(f)
    lines = [ row for row in reader if "bear" in row[4].strip().lower() ]

with open('outfile.csv', "w") as outfile:
    writer = csv.writer(outfile)
    writer.writerows(lines)
