无法使用python将JSON文件从google云存储加载到bigquery

我试图将一个文件从我的Google云存储导出到Google bigquery，但遇到了很多问题

#standardSQL
import json
import argparse
import time
import uuid

from google.cloud import bigquery
from google.cloud import storage

dataset = 'dataworks-356fa'
source = 'gs://dataworks-356fa-backups/pullnupload.json'

def load_data_from_gcs(dataset, test10, source ):
    bigquery_client = bigquery.Client(dataset)
    dataset = bigquery_client.dataset('FirebaseArchive')
    table = dataset.table(test10)
    job_name = str(uuid.uuid4())

    job= bigquery_client.load_table_from_storage(
        job_name, table, "gs://dataworks-356fa-backups/pullnupload.json")
    job.source_format = 'NEWLINE_DELIMITED_JSON'
    job.begin()

    # wait_for_job(job)
    print("state of job is: " + job.state)
#     print("errors: " + job.errors)

load_data_from_gcs(dataset, 'test10', source)

当

等待作业（作业）

行未注释掉时，我收到此错误

Traceback (most recent call last): 
File "cloudtobq.py", line 42, in <module> 
load_data_from_gcs(dataset, 'test10', source) 
File "cloudtobq.py", line 38, in load_data_from_gcs 
wait_for_job(job) 
NameError: global name 'wait_for_job' is not defined

当两者都被注释掉时，这就是我接收到的内容，然后返回到原始终端屏幕

Wess-MacBook-Pro:desktop wesstephens$ python cloudtobq.py
state of job is: RUNNING
Wess-MacBook-Pro:desktop wesstephens$

您需要包括函数的定义：

您不需要打印作业。错误，因为如果作业失败，

等待作业

将引发异常

Wess-MacBook-Pro:desktop wesstephens$ python cloudtobq.py
state of job is: RUNNING
Wess-MacBook-Pro:desktop wesstephens$

def wait_for_job(job):
    while True:
        job.reload()
        if job.state == 'DONE':
            if job.error_result:
                raise RuntimeError(job.errors)
            return
        time.sleep(1)
