Python中用tkinter创建GUI时，设置窗口大小，总是报错，求各位大神指导！

from tkinter import *

root = Tk()  
root.title('My First Tk') 
root.geomtry('150x200')
root.mainloop() 

报错信息：
Traceback (most recent call last):
File "G:/Lab/01jsq/jsq/main.py", line 9, in
root.geomtry('150x200')
File "C:\Users\bitla\AppData\Local\Programs\Python\Python37-32\lib\tkinter__init__.py", line 2101, in getattr
return getattr(self.tk, attr)
AttributeError: '_tkinter.tkapp' object has no attribute 'geomtry'

真心不知道哪里出问题了，求各位大佬指导，跪谢！

问题找到了，汗，geometry()少了一个字母e

用Pycharm 可以避免这些错误
