[英]Python RecursionError: maximum recursion depth exceeded
I have a python program I wrote that moves my solar panel with the sun throughout the day.我有一个我写的 python 程序,它可以全天随着太阳移动我的太阳能电池板。 It works fine, but about twice a week I get RecursionError: maximum recursion depth exceeded
它工作正常,但大约每周两次我收到 RecursionError: maximum recursion depth exceeded
I'm pretty new to python and I've looked up Recursion Errors, it says when a function calls itself too many times, I don't see where that is happening in this program.我对 python 很陌生,我查过递归错误,它说当一个函数调用自己太多次时,我看不到这个程序中发生了什么。

You have (at least one) a loop in your code:您的代码中有(至少一个)循环:
def main_Function():
-> solar_Adjust_Active(time_To_Adjust)
-> daylight_Adjustment()
-> main_Function() -> .... # lets run that for a couple of days ...
Normally you have a main loop (fe while True:
) and call/return from functions into your main loop without recursing:通常你有一个主循环(fe
while True:
)并且从函数调用/返回到你的主循环而不递归:
Pseudocode:伪代码:
def resetToStart():
move panels to sunrise position
return
def movePanel():
get_currnt_optimal_position_for_datetime
move_to_that_position
return
resetToStart() # start at a well known position
while True:
if NightTime: # sun is down
resetToStart()
sleep till daytime
elif DayTime: # sun is up
movePanel()
sleep some till adjustment needed
