How to get the user input values without calling the entry label name or using the get() methid in python tkinter
问题
I can help you with the translation. Here's the translated code:
from tkinter import *
matrix = [[]]
# 验证用户输入是否为数字
def number():
input = int(E1.get())
# 如果用户输入是数字，则创建一个输入矩阵
try:
int(input)
for x in range(input):
for y in range(input):
matrixInput = Entry(root, bg="white")
matrixInput.grid(row=10+x, column=1+y, padx=5, pady=5)
B2 = Button(root, text="提交", font=40, command=storeMatrix)
B2.grid(row=20, column=1)
except ValueError:
L2.config(text="您没有输入数字")
def storeMatrix():
temp = []
for x in range(input):
for y in range(input):
temp.append(matrixInput.get())
root = Tk()
L1 = Label(root, text="有多少人", font=40)
L1.grid(row=0, column=0)
E1 = Entry(root, bg="white")
E1.grid(row=0, column=1)
L2 = Label(root, text='')
L2.grid(row=3, column=1)
B1 = Button(root, text="提交", font=40, command=number)
B1.grid(row=2, column=1)
root.mainloop()
I've translated the code, replacing the text within the code with Chinese text while leaving the code structure intact.

I'm pretty new to using python tkinter and I have created a matrix of entries based on user input. Like for example if the user types in 3, the program will output a 3x3 matrix. The issue I'm having is that I'm not able to figure out to extract the user data from the matrix of entries. This is my code:
from tkinter import *
matrix = [[]]
#Validate that the user entered a number
def number():
input = int(E1.get())
#Creates a matrix of entries if the user entered a number
try:
int(input)
for x in range(input):
for y in range(input):
matrixInput = Entry(root, bg = "white")
matrixInput.grid(row=10+x, column=1+y, padx=5, pady=5)
B2 = Button(root, text="Submit", font = 40, command=storeMatrix)
B2.grid(row=20, column=1)
except ValueError:
L2.config(text = "You did not enter a number")
def storeMatrix():
temp = []
for x in range(input):
for y in range(input):
temp.append(matrixInput.get())
root = Tk()
L1 = Label(root, text="How many people", font = 40)
L1.grid(row=0, column=0)
E1 = Entry(root, bg = "white")
E1.grid(row=0, column=1)
L2 = Label(root, text = '')
L2.grid(row=3, column=1)
B1 = Button(root, text="Submit", font = 40, command=number)
B1.grid(row=2, column=1)
root.mainloop()
Any help on how to fix this issue would be amazing. Thank you.

你需要将所有的输入字段保存在一个全局变量中。matrixInput 是局部于 number() 函数的，并且仅包含最后创建的输入。
你可以使用 matrix 列表来实现这个目标。
matrix = []
def number():
input = int(E1.get())
# 如果用户输入了一个数字，则创建一个输入矩阵
try:
int(input)
for x in range(input):
matrixRow = []
for y in range(input):
matrixInput = Entry(root, bg="white")
matrixInput.grid(row=10+x, column=1+y, padx=5, pady=5)
matrixRow.append(matrixInput)
matrix.append(matrixRow)
B2 = Button(root, text="Submit", font=40, command=storeMatrix)
B2.grid(row=20, column=1)
except ValueError:
L2.config(text="您没有输入一个数字")
def storeMatrix():
temp = []
for x in range(input):
for y in range(input):
temp.append(matrix[x][y].get())

You need to save all the input fields in a global variable. matrixInput is local to the number() function, and also only contains the last input that was created.
You can use the matrix list for this.
matrix = []
def number():
input = int(E1.get())
#Creates a matrix of entries if the user entered a number
try:
int(input)
for x in range(input):
matrixRow = []
for y in range(input):
matrixInput = Entry(root, bg = "white")
matrixInput.grid(row=10+x, column=1+y, padx=5, pady=5)
matrixRow.append(matrixInput)
matrix.append(matrixRow)
B2 = Button(root, text="Submit", font = 40, command=storeMatrix)
B2.grid(row=20, column=1)
except ValueError:
L2.config(text = "You did not enter a number")
def storeMatrix():
temp = []
for x in range(input):
for y in range(input):
temp.append(matrix[x][y].get())
