从单个命令的多行输出中读取多个变量

import subprocess

# 运行命令，并将输出保存到变量output中
output = subprocess.check_output('command', shell=True).decode('utf-8')

# 将output按行分割成列表
lines = output.splitlines()

# 读取每行中的多个变量
for line in lines:
    # 假设每行的格式为：var1=value1, var2=value2, var3=value3
    variables = line.split(', ')
    var1 = var2 = var3 = ''

    for var in variables:
        name, value = var.split('=')
        if name == 'var1':
            var1 = value
        elif name == 'var2':
            var2 = value
        elif name == 'var3':
            var3 = value

    # 打印读取到的变量值
    print(f'var1: {var1}')
    print(f'var2: {var2}')
    print(f'var3: {var3}')
