Python 3.x 在同一循环完成第一次迭代后，尝试从头开始迭代循环

我有两个嵌套的“for循环”，我正在尝试重新启动第一个循环以从头开始迭代，一旦它的嵌套循环按照if语句成功完成迭代。 但是，如果嵌套循环满足“else”条件，则外部循环应定期继续其迭代。 我试图告诉代码，如果在屏幕上找到的关键字以创建的关键字开始，直到该点继续，否则将在最后一个索引处更改后者，在那里他们停止匹配

这是我已经尝试过的，但是第一个（外部）循环继续通过字母进行迭代，而不是从头开始

import time
from bs4 import BeautifulSoup
from selenium import webdriver
browser = webdriver.Chrome('chromedriver.exe')
keyList = ['a','b','c','d']
mainUrl = "https://www.amazon.com/"
browser.get(mainUrl)
searchInput = browser.find_element_by_xpath('//input[@id="twotabsearchtextbox"]')
searchInput.clear()
keyword = str()

# I WANT THE LOOP TO RESTART FROM HERE ONCE THE NESTED LOOP IS FINISHED

for keyChar in keyList:
    searchInput.send_keys(keyChar)
    time.sleep(2)
    searchSoup = BeautifulSoup(browser.page_source, "html.parser")
    searchResult = searchSoup.find_all('div', attrs={'id':'suggestions-template'})
    results = searchResult[0].find_all('div', attrs={'class':'s-suggestion'})
    keyword = keyword + keyChar
    print("This is the keyword so far:>>>>   ",keyword)
    time.sleep(2)

    for data_result in results:
        data_keywords = BeautifulSoup(str(data_result),"html.parser")
        keywords_on_screen = data_keywords.find("div", class_="s-suggestion")["data-keyword"]
        print(keywords_on_screen)

        if keywords_on_screen.startswith(keyword):
            print('ALL GOOD')
        else:
            print('Condition not met, moving on next letter')
            continue

我相信您想要的是继续最外层的循环，如果嵌套循环中的

else

条件得到满足。如果未满足

else

条件，则从头开始重新启动最外层的循环

import time
from bs4 import BeautifulSoup
from selenium import webdriver
browser = webdriver.Chrome('chromedriver.exe')
keyList = ['a','b','c','d']
mainUrl = "https://www.amazon.com/"
browser.get(mainUrl)
searchInput = browser.find_element_by_xpath('//input[@id="twotabsearchtextbox"]')
searchInput.clear()
keyword = str()

# I WANT THE LOOP TO RESTART FROM HERE ONCE THE NESTED LOOP IS FINISHED

for keyChar in keyList:
    searchInput.send_keys(keyChar)
    time.sleep(2)
    searchSoup = BeautifulSoup(browser.page_source, "html.parser")
    searchResult = searchSoup.find_all('div', attrs={'id':'suggestions-template'})
    results = searchResult[0].find_all('div', attrs={'class':'s-suggestion'})
    keyword = keyword + keyChar
    print("This is the keyword so far:>>>>   ",keyword)
    time.sleep(2)

    for data_result in results:
        data_keywords = BeautifulSoup(str(data_result),"html.parser")
        keywords_on_screen = data_keywords.find("div", class_="s-suggestion")["data-keyword"]
        print(keywords_on_screen)

        if keywords_on_screen.startswith(keyword):
            print('ALL GOOD')
        else:
            print('Condition not met, moving on next letter')
            continue

试试：-

import time
from bs4 import BeautifulSoup
from selenium import webdriver
browser = webdriver.Chrome('chromedriver.exe')
keyList = ['a','b','c','d']
mainUrl = "https://www.amazon.com/"
browser.get(mainUrl)
searchInput = browser.find_element_by_xpath('//input[@id="twotabsearchtextbox"]')
searchInput.clear()
keyword = str()
ctr = 0
x = 0

# I WANT THE LOOP TO RESTART FROM HERE ONCE THE NESTED LOOP IS FINISHED

while x < len(keyList):
    keyChar = keyList[x]
    searchInput.send_keys(keyChar)
    time.sleep(2)
    searchSoup = BeautifulSoup(browser.page_source, "html.parser")
    searchResult = searchSoup.find_all('div', attrs={'id':'suggestions-template'})
    results = searchResult[0].find_all('div', attrs={'class':'s-suggestion'})
    keyword = keyword + keyChar
    print("This is the keyword so far:>>>>   ",keyword)
    time.sleep(2)

    for data_result in results:
        data_keywords = BeautifulSoup(str(data_result),"html.parser")
        keywords_on_screen = data_keywords.find("div", class_="s-suggestion")["data-keyword"]
        print(keywords_on_screen)

        if keywords_on_screen.startswith(keyword):
            print('ALL GOOD')
            ctr = 1
        else:
            print('Condition not met, moving on next letter')
            ctr = 0
            continue
    if ctr is not 1:
        x += 1

从bs4导入BeautifulSoup
从selenium导入webdriver

当x>>”，关键字）
时间。睡眠（2）
对于结果中的数据_结果：
data\u keywords=BeautifulSoup（str（data\u result），“html.parser”）
关键词屏幕上的关键词=数据关键词。查找（“div”，class=“s-suggestion”）[“数据关键词”]
打印（屏幕上的关键字）
如果屏幕上有关键字，则开始使用（关键字）：
打印（“一切正常”）
ctr=1
其他：
打印（'不满足条件，继续下一个字母'）
ctr=0
持续
如果ctr不是1：
x+=1

如果满足嵌套的

条件，则最外层的循环将无限执行，直到嵌套的
条件满足为止；否则，如果不满足该条件，则最外层的循环将正常执行，并在列表
KeyList
的所有元素用尽后终止
