Question

我试图搜索这个主题，但它一直很混乱，因为我不使用/非常了解stdout / stderr ...但是，我现在有这个代码将列表打印到控制台。有人可以向我解释如何将其直接打印到GUI文本框上吗？我的代码：

from tkinter import *
import math

class TimeGenerator:

    def __init__(self,master):
        frame = Frame(master)
        frame.grid()
        label_iso = Label(root, text="Isotope A, Element")
        label_vol = Label(root, text="Voltage")
        label_range = Label(root, text="Charge Range")

        entry_iso = Entry(root)
        entry_vol = Entry(root)
        entry_range = Entry(root)

        label_iso.grid(row=0, sticky=E)
        label_vol.grid(row=1, sticky=E)
        label_range.grid(row=2, sticky=E)

        entry_iso.grid(row=0, column=1)
        entry_vol.grid(row=1, column=1)
        entry_range.grid(row=2,column=1)

        button = Button(root, text='Time Range', command=self.calculateTime)
        button.grid(row=3, columnspan=2)

        self.iso = entry_iso
        self.vol = entry_vol
        self.r = entry_range

    def calculateTime(self):
        x = 5

        self.iso = self.iso.get().replace(" ", "")
        list = []
        for e in self.iso.split(","):
            list.append(e)

        f = open("/Users/LazyLinh/PycharmProjects/mass.mas12.txt", "r")
        i = 0
        while (i < 40):
            header = f.readline()
            i += 1
        self.mass = 0

        for line in f:
            line = line.strip()
            columns = line.split()
            if (list[0] == columns[3]):
                if (list[1] == columns[4]):
                    if (len(columns) == 16):
                        self.mass = float(columns[13].replace("#","")) + float(columns[14].replace("#",""))
                    else:
                        self.mass = float(columns[12].replace("#","")) + float(columns[13].replace("#",""))

        self.r = self.r.get().replace(" ", "")
        tup = tuple(int(x) for x in self.r.split(","))

        list = []
        for q in range(tup[0], tup[1] + 1):
            y = x * math.sqrt(self.mass / (2 * q * float(self.vol.get())))
            list.append(y)
        i = tup[0]
        for time in list:
            print(i, ':', time)
            i = i + 1


root = Tk()
b = TimeGenerator(root)
root.mainloop()

谢谢！

在代码中的某处，您需要创建一个文本小部件：

class TimeGenerator:

    def __init__(self,master):
        ...
        self.text = Text(...)
        ...

稍后，使用文本小部件的insert方法而不是print语句：

    for time in list:
        self.text.insert("end", "%d: %s\n" % (i, time))
        i = i + 1
