Python在Google Colab中"期望有一个缩进的块"

Question

我对python完全陌生。如果有人知道我的代码是怎么回事，我需要帮助吗？

app_reviews = []
for ap in tqdm(app_packages):
for score in list(range(1,6)):
for sort_order in [Sort.MOST_RELEVANT, Sort.NEWEST]:
rvs, _ = reviews(
ap,
lang='en',
country='us',
sort=sort_order,
count= 200 if score == 3 else 100,
filter_score_with=score
)
for r in rvs:
r['sortOrder'] = 'most_relevant' if sort_order == Sort.MOST_RELEVANT else 'newest'
r['appId'] = ap
app_reviews.extend(rvs)

出现错误

File "<ipython-input-33-c40fb4fad079>", line 3
for score in list(range(1,6)):
^ IndentationError: expected an indented block

您需要注意缩进，这在python中非常重要。与其他语言不同的是，当你得到一个条件块时，你需要把它像括号一样制表。

app_reviews = []
for ap in tqdm(app_packages):
for score in list(range(1,6)):
for sort_order in [Sort.MOST_RELEVANT, Sort.NEWEST]:
rvs, _ = reviews(
ap,
lang='en',
country='us',
sort=sort_order,
count= 200 if score == 3 else 100,
filter_score_with=score
)

for r in rvs:
r['sortOrder'] = 'most_relevant' if sort_order == Sort.MOST_RELEVANT else 'newest'
r['appId'] = ap
app_reviews.extend(rvs)
