【问题描述】：

我对编码很陌生，所以如果我的代码看起来像垃圾（可能确实如此），请耐心等待。我只希望我的输出出现在我制作的 GUI 中而不是 shell 中。如何修改我的代码以实现这一点？

import random
from tkinter import *

# Attributes
age = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20",
       "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39",
       "40", "41", "42", "43", "44", "45", "46", "47", "48", "49", "50", "51", "52", "53", "54", "55", "56", "57", "58",
       "59", "60", "61", "62", "63", "64", "65", "66", "67", "68", "69", "70", "71", "72", "73", "74", "75", "76", "77",
       "78", "79", "80", "81", "82", "83", "84", "85", "86", "87", "88", "89", "90", "91", "92", "93", "94", "95", "96",
       "97", "98", "99", "100", ]
country = ["United States", "Brazil", "Mexico", "China", "Japan", "Canada", "France", "Germany"]
male_name = ["Joe", "Eden", "Diego", "Anthony", "Jarod", "Kique", "Austin", "Hunter"]
female_name = ["Haley", "Ariana", "Sarah", "Jackie", "Serena"]
gender_male = "Male"
gender_female = "Female"

# Random Generation
def print_start_life(event):
    Text(window, text=print(random.choice(age)), font=("Arial Bold", 16))
    Text(window, text=print(random.choice(country)), font=("Arial Bold", 16))
    Text(window, text=print(random.choice(male_name or female_name)), font=("Arial Bold", 16))
    if male_name:
        Text(window, text=print(gender_male), font=("Arial Bold", 16))
    elif female_name:
        Text(window, text=print(gender_female), font=("Arial Bold", 16))


# GUI
window = Tk()
window.title("Random Life")
window.geometry('800x500')
lbl = Label(window, text="Do you want to play Random Life?", font=("Arial Bold", 25))
lbl.grid(column=0, row=0)

btn = Button(window, text="Yes")
btn.bind("<Button-1>", print_start_life)
btn.grid(column=1, row=0)
window.mainloop()

【问题讨论】：

删除所有 print(...) 的调用 text=print(...)，例如text=random.choice(age).

标签： python user-interface tkinter window output

【解决方案1】：

您的代码中有几个问题。您所说的问题是由于在text=print(...) 中调用print(...)。不需要调用print(...)，只需将print(...)的参数赋值给text即可。

您也不应该在每次单击Yes 按钮时重新创建Text 小部件。您应该创建 Label 小部件以显示一次随机结果，然后在 print_start_life() 函数中更改其文本。

以下是您的代码的修改版本：

import random
from tkinter import *

# Attributes
age = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20",
       "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39",
       "40", "41", "42", "43", "44", "45", "46", "47", "48", "49", "50", "51", "52", "53", "54", "55", "56", "57", "58",
       "59", "60", "61", "62", "63", "64", "65", "66", "67", "68", "69", "70", "71", "72", "73", "74", "75", "76", "77",
       "78", "79", "80", "81", "82", "83", "84", "85", "86", "87", "88", "89", "90", "91", "92", "93", "94", "95", "96",
       "97", "98", "99", "100", ]
country = ["United States", "Brazil", "Mexico", "China", "Japan", "Canada", "France", "Germany"]
male_name = ["Joe", "Eden", "Diego", "Anthony", "Jarod", "Kique", "Austin", "Hunter"]
female_name = ["Haley", "Ariana", "Sarah", "Jackie", "Serena"]
gender_male = "Male"
gender_female = "Female"

# Random Generation
def print_start_life(event=None):
    selected_age.config(text=random.choice(age))
    selected_country.config(text=random.choice(country))
    name = random.choice(male_name+female_name)
    selected_name.config(text=name)
    gender.config(text=gender_male if name in male_name else gender_female)

# GUI
window = Tk()
window.title("Random Life")
window.geometry('800x500')
lbl = Label(window, text="Do you want to play Random Life?", font=("Arial Bold", 25))
lbl.grid(column=0, row=0)

btn = Button(window, text="Yes", command=print_start_life)
#btn.bind("<Button-1>", print_start_life)
btn.grid(column=1, row=0)

frm = Frame(window)
font1 = ("Arial", 16)
font2 = ("Arial Bold", 16)
Label(frm, text='Age:', font=font1).grid(row=0, column=0, sticky=E)
selected_age = Label(frm, font=font2)
selected_age.grid(row=0, column=1, sticky=W)

Label(frm, text='Country:', font=font1).grid(row=1, column=0, sticky=E)
selected_country = Label(frm, font=font2)
selected_country.grid(row=1, column=1, sticky=W)

Label(frm, text='Name:', font=font1).grid(row=2, column=0, sticky=E)
selected_name = Label(frm, font=font2)
selected_name.grid(row=2, column=1, sticky=W)

Label(frm, text="Gender:", font=font1).grid(row=3, column=0, sticky=E)
gender = Label(frm, font=font2)
gender.grid(row=3, column=1, sticky=W)

frm.grid(row=1, sticky=W)

window.mainloop()

【解决方案2】：

我从未使用过 tkinter，但我很确定这是答案：

def print_start_life(event):
    Text(window, text=str(random.choice(age)), font=("Arial Bold", 16))
    Text(window, text=str(random.choice(country)), font=("Arial Bold", 16))
    Text(window, text=str(random.choice(male_name or female_name)), font=("Arial Bold", 16))
    if male_name:
        Text(window, text=str(gender_male), font=("Arial Bold", 16))
    elif female_name:
        Text(window, text=str(gender_female), font=("Arial Bold", 16))

在我看来，您的文本对象只是在调用打印函数，而不是为文本对象分配一个字符串。

【讨论】：

如果这个答案是正确的，我会推荐它并将其标记为接受:)

【解决方案3】：

您不能使用 print 输出到 Tkinter GUI。

您还使用的 Text() 正在创建一个包含内容的文本框，该文本框可以通过多种方式进行配置，也可以在 GUI 中进行编辑，我认为您更希望只输出结果。无论哪种方式，我都编写了 Text() 以及使用 Label() 输出不可编辑版本的替代方法。但是，您必须找到一种使用 Label 的方法来每次清除先前的输出，正如您在输出中看到的那样，它们相互堆叠。
