Question

您可以在此处关注PyCharm的文档：https://www.jetbrains.com/help/pycharm/2017.1/attaching-to-local-process.html我想附加到本地进程以进行调试。

所以我只是为了演示而在run.py文件中写了一些虚拟代码而没有任何实际用途：

package ui;

import java.util.List;
import java.util.Random;
import java.util.function.Function;
import java.util.stream.Collectors;
import java.util.stream.IntStream;

import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.value.ObservableValue;
import javafx.scene.Scene;
import javafx.scene.control.CheckBox;
import javafx.scene.control.TableCell;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.ComboBoxTableCell;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import model.DataModel;
import model.Person;

public class ConstrainedModelDemo extends Application {

    @Override
    public void start(Stage primaryStage) {
        DataModel model = new DataModel();

        List<String> guilds = IntStream.rangeClosed(1, 5).mapToObj(i -> "Guild "+i).collect(Collectors.toList());
        Random rng = new Random();
        List<Person> population = IntStream.rangeClosed(1,  100).mapToObj(i -> new Person("Person "+i, guilds.get(rng.nextInt(guilds.size())))).collect(Collectors.toList());

        model.getPopulation().setAll(population);

        TableView<Person> table = new TableView<>();
        table.setEditable(true);
        table.getItems().addAll(population);


        table.getColumns().add(column("Name", Person::nameProperty));
        TableColumn<Person, String> guildColumn = column("Guild", Person::guildProperty);
        guildColumn.setCellFactory(ComboBoxTableCell.forTableColumn(guilds.toArray(new String[guilds.size()])));
        table.getColumns().add(guildColumn);

        TableColumn<Person, Boolean> kingCol = new TableColumn<>("King");
        kingCol.setCellValueFactory(cellData -> {
            Person p = cellData.getValue();
            return Bindings.createBooleanBinding(() -> 
                p == model.getKings().get(p.getGuild()), p.guildProperty(), model.getKings());
        });

        kingCol.setCellFactory(tc -> new TableCell<Person, Boolean>() {
            private final CheckBox checkBox = new CheckBox();

            {
                checkBox.setOnAction(e -> {
                    if (checkBox.isSelected()) {
                        model.makeKing(table.getItems().get(getIndex()));
                    } else {
                        model.getKings().remove(table.getItems().get(getIndex()).getGuild());
                    }
                });
            }

            @Override
            protected void updateItem(Boolean item, boolean empty) {
                super.updateItem(item, empty);
                if (empty) {
                    setGraphic(null);
                } else {
                    checkBox.setSelected(item);
                    setGraphic(checkBox);
                }
            }
        });
        table.getColumns().add(kingCol);

        TableView<String> kingTable = new TableView<>();
        kingTable.getItems().addAll(guilds);
        kingTable.getColumns().add(column("Guild", guild -> new SimpleStringProperty(guild)));
        kingTable.getColumns().add(column("King", guild -> Bindings.createStringBinding(() -> {
            if (guild == null) return null ;
            Person king = model.getKings().get(guild);
            if (king == null) return null ;
            return king.getName() ;
        }, model.getKings())));

        BorderPane root = new BorderPane(table);
        root.setRight(kingTable);

        Scene scene = new Scene(root, 600, 600);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    private <S,T> TableColumn<S,T> column(String title, Function<S, ObservableValue<T>> prop) {
        TableColumn<S,T> col = new TableColumn<>(title);
        col.setCellValueFactory(cellData -> prop.apply(cellData.getValue()));
        return col ;
    }

    public static void main(String[] args) {
        launch(args);
    }
}

我可以通过Pycharm附加到脚本中，我是从windows cmd开始的：python running.py

然而，PyCharm只显示它在控制台部分中实际打印的内容，而我无法在Pycharm中提供任何形式的源代码，任何关于为什么我不能步进或调试我的代码的想法解释器在IDE旁边的cmd中运行脚本时添加断点吗？

由于

[编辑] cmd中发生了什么：

import time

var_not_in_loop_below = 78
counter = 0
while True:
    counter += 1
    if counter <= 1:
        dummy_text = "Dummy"
    else:
        dummy_text = "Dummies"
    print(str(counter) + " " + dummy_text)
    time.sleep(2)
    loop_var = 42

在Pycharm中

$  C:\Python278\python.exe running.py  
1 Dummy                                
2 Dummies                              
3 Dummies                              
4 Dummies                              
5 Dummies                              
6 Dummies                              
7 Dummies                              
8 Dummies                              
9 Dummies                              
10 Dummies                             
11 Dummies                             
12 Dummies                             
13 Dummies                             
14 Dummies                             
15 Dummies                             
16 Dummies

想知道问题是否与以下这一行有关：
