PySimpleGUI调用window.Read()出现expected integer but got "New"错误

报错核心是font参数的格式不符合要求。PySimpleGUI的font参数仅支持两种合法格式：

• 字符串格式："字体名 字号 可选样式"，例如"Times New Roman 16 bold"
• 元组格式：(字体名字符串, 字号整数, 可选样式字符串)，例如("Times New Roman", 16, "bold")

你代码里的错误点：
第二个窗口（发牌页面）的sg.Text('The dealer has dealt the cards:', font=('Times New Roman')) 中，('Times New Roman') 不是元组，只是被括号包裹的普通字符串，等价于直接传入"Times New Roman"。PySimpleGUI解析时会按空格拆分这个字符串，把拆分出的第二个值New当成字号尝试转成整数，就触发了expected integer but got "New"的报错。

将发牌页面的font参数补全字号即可，你可以根据需求调整字号大小，示例修改如下：

# 原错误写法
# [sg.Text('The dealer has dealt the cards:', font=('Times New Roman'))],
# 修改后写法，字号可自行调整
[sg.Text('The dealer has dealt the cards:', font=('Times New Roman', 12))],

修改后完整可运行代码：

import PySimpleGUI as sg
import random

# 全局变量定义
deck = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
hand = []
dealer_hand = []
random1 = random.randint(1,10)
random2 = random.randint(1,10)
dealer1 = random.randint(1,10)
dealer2 = random.randint(1,10)

# 欢迎页布局
welcome =  [ 
    [sg.Text('Welcome to blackjack', text_color='#000000', font=('Times New Roman', 16,'bold'))],
    [sg.Text('Rules: You will be dealt 2 cards and the same for the dealer. The dealer will', text_color='#000000')],
    [sg.Text(' only reveal one of his cards. Your objective is to reach close to 21 without crossing it', text_color='#000000')],
    [sg.Text(' Aces can be 1 or 11, all face cards are 10. If you choose to stand, your total should be more than the dealer', text_color='#000000')],
    [sg.Button('Start!')]
]
window = sg.Window('Welcome', background_color = '#FFFFFF').Layout(welcome)
window.read()
window.close()

# 发牌页布局
first = [ 
    [sg.Text('The dealer has dealt the cards:', font=('Times New Roman', 12))],
    [sg.Text(f'Your two starting cards are {random1} and {random2}')],
    [sg.Text(f'Dealer shows his faced up card: {dealer1}')],
    [sg.Button('Hit'), sg.Button('Stand')] 
]
window = sg.Window('First set', first)
event, values = window.Read()
print(event)
window.close()
