下面这个函数。有时候运行不正常显示：
translate_zoo_file("es",315)
raceback (most recent call last):
File "D:\python\1\hello.py", line 68, in <module>
translate_zoo_file("es",315)
File "D:\python\1\hello.py", line 23, in translate_zoo_file
translation = translator.translate(line, src='en', dest=language)
File "C:\Users\2\AppData\Local\Programs\Python\Python39\lib\site-packages\googletrans\client.py", line 222, in translate
translated_parts = list(map(lambda part: TranslatedPart(part[0], part[1] if len(part) >= 2 else []), parsed[1][0][0][5]))
TypeError: 'NoneType' object is not iterable
但是当参数不是es，是de或fr时一切正常。
translate_zoo_file("de",315)
translate_zoo_file("fr", 315)
这样就一切正常。
函数如下：
def translate_zoo_file(language,number):
# 设置代理
os.environ['HTTP_PROXY'] = 'http://127.0.0.1:7897'
os.environ['HTTPS_PROXY'] = 'http://127.0.0.1:7897'
# 初始化翻译器
translator = Translator()
# 读取zoo.txt前number行
with open('zoo.txt', 'r', encoding='utf-8') as f:
lines = [line.strip() for line in f.readlines()[:number]]
# 翻译
translated_lines = []
for line in lines:
if line: # 跳过空行
translation = translator.translate(line, src='en', dest=language)
translated_lines.append(translation.text)
# 写入de.txt
with open(f'{language}.txt', 'w', encoding='utf-8') as f:
f.write('\n'.join(translated_lines))
# 删除zoo.txt中的前number行
with open('zoo.txt', 'r', encoding='utf-8') as f:
remaining_lines = f.readlines()[number:]
with open('zoo.txt', 'w', encoding='utf-8') as f:
f.writelines(remaining_lines)
print(f"翻译完保存{language}.txt，已从zoo.txt中删除已翻译的{number}行")
