『壹』 python+selenium怎麼讀取csv中的數據進行列表循環登錄自動化參數登錄
為了參數化csv文件中的數據，需要做到兩點：
一是逐行讀取：用到列表
二是根據列名獲取對應單元格的值：用到字典
import csv
bid_info = csv.DictReader(open('bid_info.csv','r'))
dict_data = []
for lines in bid_info:
if bid_info.line_num == 1:
continue
else:
dict_data.append(lines)
row_num = len(dict_data)
# print('this is all the data---' + str(dict))
#循環讀取每一行
i = 0
while(i < row_num):
print('this is'+str(i)+'row----'+ str(dict_data[i]))
print(dict_data[i]['a'])
i += 1
『貳』 Python如何用列表的數據循環處理
L = ['地區1', '塵燃培地區2', '地區3', '地區4', '地區5', '地區派唯6', '地區段廳7']
for val in L:
# 進行操作邏輯
print(val)
『叄』 python循環怎麼用多線程去運行
背景：Python腳本：讀取文件中每行，放入列表中；循環讀取列表中的每個元素，並做處理操作。
核心：多線程處理單個for循環函數調用
模塊：threading
第一部分：
：多線程腳本 (該腳本只有兩個線程，t1循環次數<t2)#!/usr/bin/env python#-*- coding: utf8 -*- import sysimport timeimport stringimport threadingimport datetimefileinfo = sys.argv[1] # 讀取文件內容放入列表host_list = []port_list = [] # 定義函數：讀取文件內容放入列表中def CreateList(): f = file(fileinfo,'r') for line in f.readlines(): host_list.append(line.split(' ')[0]) port_list.append(line.split(' ')[1]) return host_list return port_list f.close() # 單線程 循環函數，注釋掉了#def CreateInfo(): # for i in range(0,len(host_list)): # 單線程：直接循環列表# time.sleep(1)# TimeMark = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S')# print "The Server's HostName is %-15s and Port is %-4d !!! [%s]" % (host_list[i],int(port_list[i]),TimeMark)# # 定義多線程循環調用函數def MainRange(start,stop): #提供列表index起始位置參數 for i in range(start,stop): time.sleep(1) TimeMark = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S') print "The Server's HostName is %-15s and Port is %-4d !!! [%s]" % (host_list[i],int(port_list[i]),TimeMark) # 執行函數，生成列表CreateList()# 列表分割成：兩部分 mid為列表的index中間位置mid = int(len(host_list)/2) # 多線程部分threads = []t1 = threading.Thread(target=MainRange,args=(0,mid))threads.append(t1)t2 = threading.Thread(target=MainRange,args=(mid,len(host_list)))threads.append(t2) for t in threads: t.setDaemon(True) t.start()t.join()print "ok"
以上是腳本內容！！！
