hi，i download your code and debug in my laptop，but i face IndexError: list index out of range

[yuantianwen]

`def main():
B = BTree(2) ------ i changed

# Insert
customNo = 20   ------  i changed
for i in range(1,customNo+1):
    B.insert((i, randint(i, 5 * i)))
B.printTree(B.root)
print()

`

when i run，i get the following error：
`E:\workspace\PycharmProjects\B_and_Bplus_Tree\venv\Scripts\python.exe E:/workspace/PycharmProjects/B_and_Bplus_Tree/B-Tree.py

There might have been some edge cases that I overlooked

@yuantianwen I fixed some stuff in B-Tree, do test it out and let me know if you still get any errors
