python中不区分大小写的CSV查询

Question

我有弗吉尼亚道路上动物碰撞的数据集。 我正在尝试提取涉及熊的所有碰撞。 在我的数据集中，使用至少三种不同的大小写组合（即Bear，bear，BEAR）键入bear。 以下是我用来提取熊碰撞的代码：

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)

我该如何区分大小写？

Answer 1

尝试这个：

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)
