用户输入变量以在以后的函数中使用

Question

我想制作一个程序，允许用户选择股票代码和其他输入，然后获取实时数据，这些数据会立即返回程序并显示股票信息和其他内容。

然后用户应该能够选择股票以及开始和结束日期，并查看这些日期的一些基本股票信息。该代码本身可以工作，但我一直在努力使用 GUI 为 stock 程序提供输入。

Answer 1

my_variable = input('enter your name: ') # Ari
print(my_variable)
>>> 'Ari'

my_variable = input('enter a number: ') # 10
print(my_variable)
>>> '10'

# Getting an actual integer, not as a string
my_variable = int(input('enter a number: ')) # 10
print(my_variable)
>>> 10
