[英]in tkinter how do i get a number into an entry
Im a beginner in Python and running into the following problem:我是 Python 初学者,遇到以下问题:
for an assignment i need to get the number that gets inserted into text1, then when i push the button pk<<<kw multiply it by 1.36 and insert it into text2.对于作业,我需要获取插入 text1 的数字,然后当我按下按钮 pk<<<kw 将其乘以 1.36 并将其插入 text2。 and reverse by pressing the other button.
并按另一个按钮反转。
only i have no clue how.只有我不知道如何。
from tkinter import *
root= Tk()
root.title("python programma omrekenen")
root.geometry("300x200")
def Iets():
label = Label(text="vermogen in pk:")
label.place(x=50,y=50)
text1=IntVar()
entry1=Entry(textvariable=text1)
entry1.place(x=150,y=50)
x1=text1.get()
def Functie 10:
def Functie 11:
button=Button (text="PK>>>KW", command=Functie10)
button.place (x=50,y=100)
button=Button (text="PK<<<KW", command=functie11)
button.place (x=150,y=150)
label = Label(text="vermogen in KW:")
label.place(x=50,y=150)
text2=IntVar()
entry2=Entry(textvariable=text2)
entry2.place(x=150,y=150)
x2=text2.get()
root.mainloop()
sorry for the bad english抱歉英语不好
That little code should hopefully help you out :那个小代码应该可以帮助你:
from tkinter import *
root = Tk()
root.title("python programma omrekenen")
root.geometry("300x200")
def Iets():
Entry1 = Entry(root, bd=4)
Entry1.grid(row=1, column=2)
Entry1.delete(0, END)
Entry1.insert(0, "Insert number")
Entry2 = Entry(root, bd=4)
Entry2.grid(row=2, column=2)
Entry2.insert(0, "Result")
def multiply(entry: int):
if entry == 1:
Entry2.delete(0, END)
try:
Entry2.insert(0, f"{int(Entry1.get()) * 2}")
except ValueError:
Entry2.insert(0, f"Invalid value")
Entry1.delete(0, END)
if entry == 2:
Entry1.delete(0, END)
try:
Entry1.insert(0, f"{int(Entry2.get()) * 2}")
except ValueError:
Entry1.insert(0, f"Invalid value")
Entry2.delete(0, END)
Button1 = Button(root, text='Multiply', bd=2, bg='green', command=lambda: multiply(1))
Button1.grid(row=1, column=1)
Button2 = Button(root, text='Multiply', bd=2, bg='green', command=lambda: multiply(2))
Button2.grid(row=2, column=1)
Iets()
root.mainloop()
Not sure if thats what you ment by reverse it but yeah.. its easy to understand so you should be fine !不确定这是否是您通过反转它所提到的,但是是的..它很容易理解,所以您应该没问题!
command
is used to call a function. command
用于调用函数。
In your case , it does a multiplication on a number and gets inserted into an entry field.在您的情况下,它对数字进行乘法运算并插入到输入字段中。
Also , delete
& insert
are 2 tkinter methods clear & insert the data respectively此外,
delete
和insert
是两种 tkinter 方法分别清除和插入数据
from tkinter import *
root= Tk()
root.title("python programma omrekenen")
root.geometry("300x400")
text1=IntVar()
text2=IntVar()
def first():
entry2.delete(0,END)
entry2.insert(0,text1.get()*1.36)
def second():
entry1.delete(0,END)
entry1.insert(0,text2.get()*1.36)
label = Label(text="vermogen in pk:")
label.place(x=50,y=50)
entry1=Entry(textvariable=text1)
entry1.place(x=150,y=50)
button=Button (text="PK>>>KW", command=first)
button.place (x=50,y=100)
button=Button (text="PK<<<KW", command=second)
button.place (x=50,y=200)
label = Label(text="vermogen in KW:")
label.place(x=50,y=150)
entry2=Entry(textvariable=text2)
entry2.place(x=150,y=150)
root.mainloop()
