Python进度条混乱，如何向已经存在的循环添加进度条

标签： python python-2.7 loops progress-bar

在查看有关Python进度条的以下问题后，我仍然感到困惑： Python Progress Bar

我是Python的新手，我正在尝试向我创建的运行for循环的脚本添加进度条。循环需要花费大量时间来处理，所以我希望进度条显示循环何时运行。令我困惑的部分是，为了实现进度条，我是否已在循环内设置循环？以下是我的代码中的for循环示例：

for member in members:
    url = "http://api.wiki123.com/v1.11/member?id="+str(member) 

    header = {"Authorization": authorization_code}

    api_response = requests.get(url, headers=header)

    member_check = json.loads(api_response.text)

    member_status = member_check.get("response")

我是否需要包含代码以在此循环中添加进度条IN或是否必须包含在循环外部？感谢。

更新：我在这里提到了进度条库，但我对其他库的建议持开放态度。

一个简单的解决方案是在循环结束时<?php $server = "localhost"; $user = "root"; $pw = "root"; $db = "uwsTest"; $connect = mysqli_connect($server, $user, $pw, $db); if ($connect->connect_error) { die("Connection failed: " . $conn->connect_error); }else{ echo'success!'; } if(isset($_POST['submit'])) { ini_set('auto_detect_line_endings', true); $file = $_FILES["file"]["tmp_name"]; $handle = fopen($file, "r"); $filesop = fgetcsv($handle, 0, ","); $coldata = array(); $coldata[ "orderNumber" ] = $filesop[0]; $coldata[ "place" ] = $filesop[1]; $coldata[ "workOrderNum" ] = $filesop[2]; $table_cols = array(); /*staging*/ $table_cols[0] = //200 element array code omitted $tablenames = array("staging"); for($tableno = 0;$tableno < sizeof($tablenames);$tableno++){ $q = ""; $q2 = ""; $q3 = ""; $q4 = ""; $q5 = ""; $q6 = ""; $col_list = '`'.str_replace(',','`,`',$table_cols[$tableno]).'`'; $q .= "INSERT INTO ".$tablenames[$tableno]."

如果您想要总是打印出100个连字符，每个'％'连接1个连字符，那么您可以执行类似var ID_COLUMN=0 var URL_COLUMN=1 findings.sort(compareByColumnIndex(URL_COLUMN)) function compareByColumnIndex(index) { return function(a,b){ if (a[index] === b[index]) { return 0; } else { return (a[index] < b[index]) ? -1 : 1; } } } 的操作，并额外检查是否为最后一次迭代添加额外的破折号为偶数100。

使用enlighten库实际上非常容易。只需在循环之前创建一个进度条，然后使用循环的每个实例进行更新。使用管理器，可以为程序的其他部分提供其他进度条。

import enlighten

manager = enlighten.get_manager()
pbar = manager.counter(total=len(members), desc="Checking status", unit='members')

for member in members:
    url = "http://api.wiki123.com/v1.11/member?id="+str(member)
    header = {"Authorization": authorization_code}
    api_response = requests.get(url, headers=header)
    member_check = json.loads(api_response.text)
    member_status = member_check.get("response")
    pbar.update()

只要代码中的members有长度，就可以使用atpbar轻松完成。

您只需要用members包装atpbar：

from atpbar import atpbar

⋮

for member in atpbar(members):
    ⋮

您可以使用 tqdm 库。

你只需要修改你的循环以包含一个计数器，看这个例子：

from tqdm import tqdm
import time
startTime = time.clock()
totalCount = len(members)
for index, member in enumerate(members):
    stopTime = time.clock()
    statusBarText = tqdm.format_meter(index + 1,
                                      totalCount,
                                      stopTime - startTime,
                                      ncols=80,  # prints text 80 characters wide
                                      ascii=False)
    print(statusBarText, '\b' * 81, end='')
    startTime = time.clock()
    ... rest of the code in your loop ...
