我有一个二维列表列表，我需要根据第一个记录字段进行搜索，内容是包含正斜杠字符的字符串。

测试 arg_size 时，如果存在正斜杠字符，则搜索总是失败。为了排除故障，我对参数进行了硬编码。

提前致谢。

# -*- coding: UTF-8 -*-
bolt = {}    # create empty dictionary
thread_geometry = {}    # create empty dictionary

#  variables for record position
size = 0
dia_in = 1
dia_mm = 2
tpi_UNC = 3
pitch_UNC_in = 4
pitch_UNC_mm = 5
tpi_UNF = 6
pitch_UNF_in = 7
pitch_UNF_mm = 8
tpi_UNEF = 9
pitch_UNEF_in = 10
pitch_UNEF_mm = 11

# lookup table for bolt standards,negative values represents NULL

键盘上的斜线与桌子上的斜线不同。有不同的符号。修改您的表以将 unicode 斜杠替换为 ascii 斜杠或使用如何在 Python 中读取 Unicode 输入和比较 Unicode 字符串的规范化解决方案？

我认为你从网上复制粘贴表格的值）
