除了解析csv文件之外，还可以查看所有列，并检查是否有一个字段包含关键字（您应该search in field使用search in field而不是==因为upsabraham指出），您还可以在此处保存一些处理能力，并检查关键字在该行的某处并按原样写入该行。

# -*- coding: utf-8 -*-

in_file = 'TestDomstol.csv'
out_file = 'verdictsOutput.csv'
search = raw_input("Enter keyword: ")

with open(in_file, 'r') as verdictFileInput:
    header = verdictFileInput.next()
    with open(out_file, 'wb') as verdictFileOutput:
        verdictFileOutput.write(header)
        for line in verdictFileInput:
            if search in line:
                verdictFileOutput.write(line)
