如何将输出保存在文本文件中

Question

我使用 TextRazor 库来分析文本并将其保存在文本文件中，但是当我打开文件时它是空的

import os 
textrazor.api_key = ""
client = textrazor.TextRazor(extractors=["word","entities", "topics","sentence","words"])
response = client.analyze("Twenty-four isolates (60%) were associated with pneumonia, 14 (35%) with upper respiratory tract infections, and 2 (5%) with bronchiolitis. Cough (82.5%), fever (75%), and malaise (58.8%) ")
for entity in response.entities():
    print(entity.id, entity.relevance_score, entity.confidence_score, entity.freebase_types)
cmd = os.popen('ls -w').read() # Récupération de la sortie de ls -a dans la variable cmd
print(cmd) # Affichage de la sortie
with open('monfichier.txt', 'w') as file:
        s=str(cmd)
        file.write(s)

Answer 1

ls -w 不是有效命令，因为在 -w 之后需要一个整数。此外，不要使用os.popen：它不可移植。请改用 Python API（请参阅os.walk）。
