我在将 Python (selenium) 输出保存到 txt 文件时遇到问题

Question

我无法将输出保存到文件中。 我正在使用以下脚本（注意这是一个澳大利亚网站）：

from selenium import webdriver
import time

    chrome_path =r"C:\Users\Tom\Desktop\chromedriver.exe"
    driver = webdriver.Chrome(chrome_path)
    driver.get("https://pointsbet.com.au/basketball/NBA")

    time.sleep(2)

    driver.find_element_by_xpath("""/html/body/div[1]/div[2]/sport-competition-component/div[1]/div[2]/div[1]/div/event-list/div[1]/event/div/header/div[1]/h2/a""").click()
    time.sleep(2)


    posts = driver.find_elements_by_class_name("market")
    for post in posts:
        print(post.text)


    with open('output12.txt',mode ='w') as f:
        f.write(str(post))

txt 文件中的输出为：

<selenium.webdriver.remote.webelement.WebElement (session="af079b982b14f33d736b6745ad6e9648", element="0.8397874328987758-6")>

它应该是这样的（取决于当时的网站数据）：

正面交锋孟菲斯灰熊队 1.55 迈阿密热火队 2.53 线孟菲斯灰熊队 -4.0 1.92 迈阿密热火队 +4.0 1.92 总分超过 195.5 1.87 低于 195.5 1.96 命名一个投注功能迈克康利和马克加索尔组合获得 41+ 分 2.50

以上是脚本运行时文本的打印方式。

任何帮助都会很棒

谢谢 - 堆栈溢出的新手 - 这太棒了

Answer 1

按如下方式更正您的for循环并判断它是否适合您：注意with open(...) ...必须在for循环内部，而不是外部！ 您还需要以append模式打开文件。

for post in posts:
    print(post.text)
    with open('output12.txt',mode ='a') as f:
        f.write(post.text)

正如@Tommy 所指出的，另一种更有效的解决方案可能是：

with open('output12.txt',mode ='w') as f:    
        for post in posts:
            print(post.text)
            f.write(post.text)

Answer 2

这将为您提供您所追求的输出（内联评论）

posts = driver.find_elements_by_class_name("market")

# Open your output file
with open('output12.txt', mode='w') as f:
    # Iterate through the posts list
    for post in posts:
        # Print the output to both the screen and the file
        print(post.text)
        f.write(post.text)

出于某种原因，我无法发布我的问题，所以我想我在这里发表评论。 我需要一些关于在 python 中输出文本的帮助。

我使用 kaldi ASR 训练了一个语言模型，现在我正在尝试将它链接到 vosk API 以制作语音到文本软件。 后端引擎是 kaldi，前端工作涉及 python。 python脚本如下：

from vosk import Model, KaldiRecognizer, SetLogLevel
import os
import wave
import json

fname =  input ( "Enter audio file name: " ) 
wav = ".wav"
txt = ".txt"
transcript = fname + txt
audiofilename = fname + wav

#wav = input( "enter audio filename with extension: " )
wf = wave.open(audiofilename, "rb")
model = Model(".")
rec = KaldiRecognizer(model, wf.getframerate())

results = []
# recognize speech using vosk model

while True:
    data = wf.readframes(4000)

    if len(data) == 0:
        break

    if rec.AcceptWaveform(data):
        part_result = json.loads(rec.Result())
        results.append(part_result)
        print(rec.Result())

    else:
        print(rec.PartialResult())
part_result = json.loads(rec.FinalResult())
results.append(part_result)

# forming a final string from the words
text = ''
for r in results:
    text += r['text'] + ' '

print(f"Vosk thinks you said:\n {text}")         
#print(rec.FinalResult())

# convert list of JSON dictionaries to list of 'Word' objects
list_of_Words = []
for sentence in results:
    if len(sentence) == 1:
        # sometimes there are bugs in recognition 
        # and it returns an empty dictionary
        # {'text': ''}
        continue
    for obj in sentence['result']:
        w = custom_Word.Word(obj)  # create custom Word object
        list_of_Words.append(w)  # and add it to list

wf.close()  # close audiofile

# output to the screen
for word in list_of_words:
    print(word.to_string())``` 

The output is working correctly. Info displayed on Shell is fine.

I cant figure out how to use f.write or similar command to save the shell output (all of it or any particular output I need from the code) and save it to a text file.
