如何解决Pyhton获取无效语法错误

Question

我正在尝试键入

command = "aws ec2 describe-instances --query "Reservations[*].Instances[].{ instance_id: InstanceId, type: InstanceType, stats: State.Name, disks: BlockDeviceMappings[*].Ebs.VolumeId, p_ip: NetworkInterfaces[*].PrivateIpAddresses[].PrivateIpAddress, name: Tags[?Key == `Name`].Value, cpu: CpuOptions.CoreCount, platform: PlatformDetails}" > output.json"
os.system(command)

我在调试时出错了。有人纠正这个语法吗。

Answer 1

您必须转义双引号：

command = "aws ec2 describe-instances --query "Reservations[*].Instances[].{ instance_id: InstanceId, type: InstanceType, stats: State.Name, disks: BlockDeviceMappings[*].Ebs.VolumeId, p_ip: NetworkInterfaces[*].PrivateIpAddresses[].PrivateIpAddress, name: Tags[?Key == `Name`].Value, cpu: CpuOptions.CoreCount, platform: PlatformDetails}" > out22.json"
os.system(command)
