我执行代码时遇到以下错误:

An error occurred: <HttpError 403 when requesting https://www.googleapis.com/gmail/v1/users/me/messages/send?alt=json returned "Insufficient Permission">

这是我的代码:

我正在尝试使用pyodbc打印前10行.我知道如何使用以下内容获取第一条记录:

row = cursor.fetchall()

我尝试将其更改为:

row = cursor.fetchten()

但这没用.还有什么我可以做的吗？

我想将我在dash中制作的网站导出为静态PDF.这是我网站的代码(它只是一个包含3列的图表):

import dash
import dash_core_components as dcc
import dash_html_components as html
import pdfkit
from flask import Flask, render_template, make_response

app = dash.Dash()
app.layout = html.Div(
                className="three columns",
                children=html.Div([
                    dcc.Graph(
                        id='right-top-graph',
                        figure={
                            'data': [{
                                'x': [1, 2, 3],
                                'y': [3, 1, 2],
                                'type': 'bar'
                            }],
                            'layout': {
                                'height': 400,
                                'margin': {'l': 10, 'b': 20, 't': 0, 'r': 0}
                            }
                        }
                    ),


                ])
            )

app.css.append_css({
    'external_url': 'https://codepen.io/chriddyp/pen/bWLwgP.css'
})

if __name__ == '__main__':
    app.run_server(debug=True)

我尝试使用pdfkit将此代码添加到我的脚本中,但它不起作用(收到一个错误,告诉我render_template()需要1个位置参数但是给出了2个):

rendered = render_template('pdf_template.html',app)
pdf = pdfkit.from_string(rendered, False)

我正在尝试从我的gmail api代码中调用,以便我可以创建草稿,但我无法弄清楚从哪里获得"授权的Gmail API服务实例".这是我的代码:

def CreateDraft(service, user_id, message_body):
  CreateDraft('SERVICE THING NEEDS TO BE HERE','me','thisisbody')
  """Create and insert a draft email. Print the returned draft's message and id.

  Args:
    service: Authorized Gmail API service instance.
    user_id: User's email address. The special value "me"
    can be used to indicate the authenticated user.
    message_body: The body of the email message, including headers.

  Returns:
    Draft object, including draft id and message meta data.

  try:
    message = {'message': message_body}
    draft = service.users().drafts().create(userId=user_id, body=message).execute()

我试图从facebook页面中提取一些产品的数据并将其全部转储到文本文件中,但我发现该文件会一直覆盖数据.我不确定这是一个分页问题还是我必须制作几个文件.

这是我的代码:

#Modules
import requests
import facebook
import json

def some_action(post):
    print posts['data']
    print post['created_time']

#Token
access_token = 'INSERT ACCESS TOKEN'
user = 'walkers'

#Posts
graph = facebook.GraphAPI(access_token)
profile = graph.get_object(user)
posts = graph.get_connections(profile['id'], 'posts')

#Write
while True:
    posts = requests.get(posts['paging']['next']).json()
    #print posts

    with open('test121.txt', 'w') as outfile:
        json.dump(posts, outfile)

知道为什么会这样吗？

我想阻止用户按下“提交”按钮 30 秒，在他们将它推送到下面的脚本中之后。我该怎么做呢？这是我的代码目前的样子：

import dash
from dash.dependencies import Input, Output, State
import dash_core_components as dcc
import dash_html_components as html

app = dash.Dash()

app.layout = html.Div([
    dcc.Input(id='my-id', value='initial value', type="text"),
    html.Button('Submit', id='button'),
    html.Div(id='my-div')
])

@app.callback(
    Output(component_id='my-div', component_property='children'),
    [Input('button', 'n_clicks')],
    state=[State(component_id='my-id', component_property='value')]
)
def update_output_div(n_clicks, input_value):
    return 'You\'ve entered "{}" and clicked {} times'.format(input_value, n_clicks)

if __name__ == '__main__':
    app.run_server()

有谁知道我如何阻止用户按下按钮 30 秒？

预先感谢。

我正在尝试在我的网站中插入一个用 Flask 编写的条形图。这是我的 app.py 的样子：

from flask import Flask, render_template
app = Flask(__name__)

@app.route("/")
def index():
    return render_template('index.html', title="Mainpage")

if __name__=='__main__':
    app.run(debug=True)

这是我的条形图的样子（chart.py）：

# -*- coding: utf-8 -*-
import dash
import dash_core_components as dcc
import dash_html_components as html

external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)

app.layout = html.Div(children=[

    dcc.Graph(
        id='example-graph',
        figure={
            'data': [
                {'x': [1, 2, 3], 'y': [4, 1, 2], 'type': 'bar', 'name': 'SF'},
                {'x': [1, 2, 3], 'y': [2, 4, 5], 'type': 'bar', 'name': u'Montréal'},
            ],
        }
    ) …

我已将我的requirementst.txt 上传到dag 并在创建我的Airflow 环境时引用它。这是我的requirements.txt 的样子：

apache-airflow==1.10.12
oauth2client==4.1.3
google-api-python-client==2.2.0
Flask-AppBuilder==2.3.3
boto3==1.17.59

但是，我在气流环境中不断收到“没有名为 oauthclient 的模块”错误。如何检查 oauthclient 是否已实际安装或者 Airflow 是否未正确读取我的 requests.txt 文件？

提前致谢。

有没有办法Tweepy通过Twitter手柄或Twitter ID 提取实时推文？

我尝试过使用Twitter Streaming API但我只能通过关键字过滤推文:

import tweepy
import json

# Import the necessary methods from tweepy library
from tweepy.streaming import StreamListener
from tweepy import OAuthHandler
from tweepy import Stream

# Variables that contains the user credentials to access Twitter API 
access_token = "INSERT ACCESS TOKEN"
access_token_secret = "INSERT ACCESS TOKEN SECRET"
consumer_key = "INSERT CONSUMER KEY"
consumer_secret = "INSERT CONSUMER SECRET"

# This is a basic listener that just prints received tweets to stdout.

我正在尝试使用循环打印图表。数据在一个列表中。这是我的代码当前的样子（我在 for 循环中收到语法错误）：

import dash
import dash_core_components as dcc
import dash_html_components as html
import pandas as pd
import plotly.graph_objs as go

dfs = [pd.DataFrame({"xaxis":["thing","otherthing","anotherthing"],"yaxis":[64,14,62]}),pd.DataFrame({"xaxis":["newthing","newotherthing","newanotherthing"],"yaxis":[344,554,112]})]
external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']
app = dash.Dash(__name__, external_stylesheets=external_stylesheets)

g = 0

app.layout = html.Div(children=[
    for df in dfs:
        dcc.Graph(id='example-graph'+str(g),figure={'data': [go.Bar(x=df['xaxis'],y=df[("yaxis")],name="yaxis")]})
    ]
    g = g + 1)

if __name__ == '__main__':
    app.run_server(debug=True)

我希望它看起来像这样：

我该怎么做呢？

提前致谢。

编辑 08/03/19：我知道我可以在下面的两个图表中手动编码，但我希望将其放入循环中，因为将来我可能会在一页上显示 2 个以上的图表。
