在循环中搜索和放入数组时遇到问题

Having Trouble Searching and Putting into Array During a Loop

所以我有一个 output.txt 文件,我要循环查找这一行“probability= 7.5098503e-03”,只要找到它,就将该概率值放入数组中。

我认为我在行中搜索 "probability" 时出现以下错误:

File "test.py", line 29, in search

if probability in line:

NameError: global name 'probability' is not defined

我也不确定我将概率放入数组中每个循环是否都能正常工作...

prob=[]

voltages = [0.3, 0.32, 0.34, 0.36, 0.38, 0.4, 0.42, 0.44, 0.46, 0.48, 0.5]
for voltage in voltages:
    update_code(voltage)
    os.system("hspice pbit.sp >output.txt")
    def search():
        with open('output.txt') as f:
            datafile = f.readlines()
        for line in datafile:
            if probability in line:
                return True
        return False
    if search():
        print('True')
        prob=[] = line
    else:
        print('False')

我希望得到这个很棒的知识社区的帮助!

您需要添加引号才能成为字符串文字

if 'probability' in line:

否则该行会期望 probability 是一个变量
