def plot(self): self.is_running = False pwd_path = os.path.abspath(os.path.join(os.getcwd(), "..")) script_path = os.path.join(pwd_path, 'callisto-test-tool\\algo_galileo_2e235eb933c9_deg90\\An_test') folder_path = os.path.join(pwd_path, 'callisto-test-tool\\source\\Test_Source_Data') os.chdir(script_path) os.system('powershell -Command "./csv_output.sh {0}"'.format(folder_path)) 怎么检测该段程序是否运行完毕

可以使用os.path.abspath(os.path.join(os.getcwd(), ".."))来获取当前工作目录的上级目录，然后将其赋值给pwd_path。所以，可以将第三行代码改为： ``` pwd_path = os.path.abspath(os.path.join(os.getcwd(), "..")) ``` 这样就能获取到当前工作目录的上级目录了。

好的，您可以在 `ExcelPlotter` 类中添加一个名为 `delete_image` 的方法，实现删除当前图像的功能。可以在该方法中调用 `self.figure.clf()` 清空当前图像，然后在界面上更新显示。下面是修改后的代码： ```python import tkinter as tk import pandas as pd import matplotlib.pyplot as plt from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg import os class ExcelPlotter(tk.Frame): def __init__(self, master=None): super().__init__(master) self.master = master self.master.title("图方便") self.file_label = tk.Label(master=self, text="Excel File Path:") self.file_label.grid(row=0, column=0, sticky="w") self.file_entry = tk.Entry(master=self) self.file_entry.grid(row=0, column=1, columnspan=2, sticky="we") self.file_button = tk.Button(master=self, text="Open", command=self.open_file) self.file_button.grid(row=0, column=3, sticky="e") self.plot_button = tk.Button(master=self, text="Plot", command=self.plot_data) self.plot_button.grid(row=1, column=2, sticky="we") self.delete_button = tk.Button(master=self, text="Delete", command=self.delete_image) self.delete_button.grid(row=1, column=3, sticky="e") self.name_label = tk.Label(master=self, text="Out Image Name:") self.name_label.grid(row=2, column=0, sticky="w") self.name_entry = tk.Entry(master=self) self.name_entry.grid(row=2, column=1, columnspan=2, sticky="we") self.save_button = tk.Button(master=self, text="Save", command=self.save_image) self.save_button.grid(row=2, column=3, sticky="e") self.figure = plt.figure(figsize=(5, 4), dpi=150) self.canvas = FigureCanvasTkAgg(self.figure, master=self) self.canvas.get_tk_widget().grid(row=4, column=0, columnspan=4, sticky="we") self.pack() def open_file(self): file_path = tk.filedialog.askopenfilename(filetypes=[("Excel Files", "*.xls")]) self.file_entry.delete(0, tk.END) self.file_entry.insert(tk.END, file_path) def plot_data(self): file_path = self.file_entry.get() if os.path.exists(file_path): data = pd.read_excel(file_path) plt.plot(data['波长(nm)'], data['吸光度'], 'k') plt.xlim(300, 1000) plt.xlabel('Wavelength(nm)', fontsize=16) plt.ylabel('Abs.', fontsize=16) plt.gcf().subplots_adjust(left=0.13, top=0.91, bottom=0.16) plt.show() def delete_image(self): if self.figure: self.figure.clf() self.canvas.draw() def save_image(self): if self.figure: file_path = tk.filedialog.asksaveasfilename(defaultextension=".png") if file_path: self.figure.savefig(file_path) root = tk.Tk() app = ExcelPlotter(master=root) app.mainloop() ``` 在界面上添加了一个名为 `Delete` 的按钮，点击该按钮会调用 `delete_image` 方法。该方法会清空当前图像并在界面上更新显示。
