は何も出力していません

Question

isinstanceを使用しているときに私のコードが何も出力していません。これはコードの最後に表示されます。 year 1とtla_2=1を入力しようとしましたが、出力はありませんでした。私のisinstanceステートメントは間違っていますか？私は間違ってループしていますか？

output = 'From Bus #: {}\tTo Bus #: {}\tTo Bus #: {}\t Area Station: {}\t VMIN: {} pu\tVMAX: {} pu\t' 
print(output.format(from_, to,name2, min_value, max_value,last_bus))

Answer 1

csv.writercsvに任意のデータ（整数、浮動小数点数、文字列を...）書き込むことができます。しかし、csv.readerは逆の操作を行いません。

last_busは、csv.readerイテレータから直接送信されるデータです。だからにはが文字列になる。

したがって、isinstanceメソッドはTrueを返すことはできません。

文字列が実際に整数かどうかを確認する方法はいくつかあります。 How can I check if a string has a numeric value in it in Python?

をあなたたら：私はそれが既に質問に答えますが、お好みの1を実装するために（他のQ &ようにリンクしている）このQ & Aをご確認の多い冗長になる、それらをここで説明しています文字列が整数を保持すると判断した場合は、int(last_bus)を整数に変換するだけです。

Answer 2

だから私はあなたの言ったことをしました。正しく出力されていますが、psspyファンクションに出力されません。

for row in data: 
    year_link, from_,to,digit,name2,tla_2,min_value,max_value,last_bus = row[7:16] 
    if isinstance(last_bus, str) and year_link==year and tla_2==location and last_bus.isdigit() is True: 
     min_value=float(min_value) 
     max_value=float(max_value) 
     last_bus=int(last_bus) 
     output = 'From Bus #: {}\tTo Bus #: {}\tLast Bus #: {}\t Area Station: {}\t VMIN: {} pu\tVMAX: {} pu\t' 
     print(output.format(from_, to,last_bus,name2, min_value, max_value)) 
     print("\n") 
     psspy.three_wnd_winding_data_3(from_,to,last_bus=int(last_bus),r"""1""",1,[_i,_i,_i,_i,_i],[_f,_f,_f,_f,_f,_f,_f,_f, max_value, min_value,_f,_f,_f]) 
    else: 
     exit
