python3.5 :Can't convert bytes to string implicitly

Question

for url_ in url_list:
    print("Processing {}...\n".format(url_))
    r_new = rq.get(url_)
    soup = bsoup(r_new.text)
    h = soup.findAll("div", {"class": "fk-review"})
    for row in h:
        reviewfile.write(str(pe) + ') \n')
        b = row.findAll("div", {"class": "rating"})

        for a in b:
            c = a.get('style').strip()
            c = ratings_string(c)

            reviewfile.write('Ratings: ' + (c) + '\n')
            local_rating = c
        c = row.findAll("a", {"class": "load-user-widget"})

        for s in c:
            f = s.get_text().strip()

            reviewfile.write("Name: " + f + '\n')
            local_user = f

        y = row.find_all("span", {"class": "review-text"})
        for u in y:
            u = u.get_text().encode('utf-8', errors='ignore').strip()
            local_review = u

            str1 = local_review.lower()

            reviewfile.write('\n' + u + '\n  \n')

            pe += 1

我正在尝试检索文本文件中的产品评论，但它显示它可以隐式地将字节转换为字符串，请帮助我......提前致谢

错误是:

Traceback (most recent call last):
  File "E:\Mtech projects\SET 2\flip.py", line 175, in <module>
    reviewfile.write('\n' + u + '\n  \n')
TypeError: Can't convert 'bytes' object to str implicitly

Answer 1

您的 u 对象已编码。
这一行就做到了u = u.get_text().encode('utf-8',errors='ignore').strip()

如果将其添加到字符串，Python会自动尝试将u转换为字符串，但会引发此 TypeError 因为它是经过编码的。

您有两个选择:要么首先不对该文本进行编码(仅适用于 u = u.get_text())，或者稍后对其进行解码，即使用 u。首先解码('utf-8')，然后您就可以使用字符串了。
