问题描述
updated_df = pd.DataFrame()
with requests.Session() as connection_session: # reuse your connection!
for follow_url in get_follow_urls(get_main_urls(),connection_session):
key = follow_url.rsplit("/")[-1].replace(".html","")
# print(f"Fetching data for {key}...")
dfs = pd.read_html(
connection_session.get(follow_url).content.decode("utf-8"),flavor="bs4",)
# https://stackoverflow.com/questions/39710903/pd-read-html-imports-a-list-rather-than-a-dataframe
for df in dfs:
df = dfs[0].T.iloc[1:,:].copy()
updated_df = updated_df.append(df)
print(updated_df)
cols = ['项目编号','转让/出租标的名称','转让方/出租方名称','转让标的评估价/年租金评估价（元）','转让底价/年租金底价（元）','受让方/承租方名称','成交价/成交年租金（元）','成交日期']
updated_df.columns = cols
updated_df.to_excel('./data.xlsx',index = False)
此代码正在打印字符串的所有文本、依赖项和位置。 我想在字符串中识别疑问词“How”。
解决方法
如果您想用 using Super::iterator; 和 #include <vector>
template< class T >
struct IsAType {};
template< class T >
class MyVectorPublic : public std::vector< T >
{
using Super = std::vector< T >;
public:
using Super::vector;
using Super::at; // function
using Super::push_back; // function
using Super::iterator; // type
// IsAType< Super::vector > t; //
};
template< class T >
class MyVectorProtected : protected std::vector< T >
{
using Super = std::vector< T >;
public:
using Super::vector;
using stdvec = typename Super::vector;
using Super::at; // function
using Super::push_back; // function
using Super::iterator; // type
// IsAType< Super::vector > t; // C2923
};
template< class T >
class MyVectorPrivate : private std::vector< T >
{
using Super = std::vector< T >;
public:
using Super::vector;
using stdvec = typename Super::vector;
using Super::at; // function
using Super::push_back; // function
using Super::iterator; // type
// IsAType< Super::vector > t; // C2923
};
int main()
{
auto vecPub = MyVectorPublic< int >::vector();
//auto vecProt = MyVectorProtected< int >::vector(); // C2247
//auto vecPriv = MyVectorPrivate< int >::vector(); // C2247
auto vecProt = MyVectorProtected< int >::stdvec();
auto vecPriv = MyVectorPrivate< int >::stdvec();
auto itPub = MyVectorPublic< int >::iterator();
auto itProt = MyVectorProtected< int >::iterator();
auto itPriv = MyVectorPrivate< int >::iterator();
}
查找令牌，请使用
tok.dep_ == 'advmod'这会打印 tok.pos_ == 'ADV'。
坚持基本知识不是更容易吗？
a = "Hello my name is Amar. How can I help you?"
Space = a.find(" ")
Q= a[:Space]
