今天老师给了我们这样一道题
“默克尔树有叶4个，自己定义叶子存放的数据，请计算默克尔树根的值。”
总的来说，还是得用tkinter
懒得自己搞死自己，决定”输入四个值”，直接一键输出后面所有的
对我这样的初学者来说，代码比较长，但分段做的话也不复杂，逻辑清晰就可以了。
下面是代码：
import tkinter
import hashlib
def mgbox1():
y1 = b1.get()
x1 = y1.encode()
hash_1 = hashlib.sha256(x1)
c1=hash_1.hexdigest()
listboxHash1.insert(0,c1)
y2 = b2.get()
x2 = y2.encode()
hash_2 = hashlib.sha256(x2)
c2 = hash_2.hexdigest()
listboxHash2.insert(0,c2)
y3 = b3.get()
x3 = y3.encode()
hash_3 = hashlib.sha256(x3)
c3 = hash_3.hexdigest()
listboxHash3.insert(0,c3)
y4 = b4.get()
x4 = y4.encode()
hash_4 = hashlib.sha256(x4)
c4 = hash_4.hexdigest()
listboxHash4.insert(0,c4)
c12 = c1+c2
h12 = c12.encode()
hash_12 = hashlib.sha256(h12)
w12=hash_12.hexdigest()
listboxHash5.insert(0,w12)
c34 = c3+c4
h34 = c34.encode()
hash_34 = hashlib.sha256(h34)
w34 = hash_34.hexdigest()
listboxHash6.insert(0, w34)
c1234 = w12+w34
u1234 = c1234.encode()
hash_1234 = hashlib.sha256(u1234)
w1234 = hash_1234.hexdigest()
listboxHash7.insert(0, w1234)
