解析一行文本以获取一个特定的数字 [英] parsing a line of text to get a specific number

问题描述

我有一行文字，格式为" some spaces variable = 7 = '0x07' some more data"

I have a line of text in the form " some spaces variable = 7 = '0x07' some more data"

我想解析它并从某些变量= 7"中获得数字7.如何在python中完成?

I want to parse it and get the number 7 from "some variable = 7". How can this be done in python?

推荐答案

我将使用更简单的解决方案，避免使用正则表达式.

I would use a simpler solution, avoiding regular expressions.

在'='上分割并在期望的位置获取值

Split on '=' and get the value at the position you expect

text = 'some spaces variable = 7 = ...'
if '=' in text:
    chunks = text.split('=')
    assignedval = chunks[1]#second value, 7
    print 'assigned value is', assignedval
else:
    print 'no assignment in line'
