多條件布爾邏輯 Python

Question

我可以獲得有關 Python 中布爾條件邏輯的更好方法的提示嗎？ 我試圖根據在starttime和endtime之間的current_time以及其他布爾邏輯來返回 True 或 False，以檢查作為 datetime 工作日數的current_day是否是周末或工作日。

一個函數似乎最適合這個？ 任何提示都可以幫助我遇到一個問題，如果Weekends或Weekdays都為False ，則意味着該事件被禁用，或者如果current_time不在starttime和endtime之間，則該事件也將被禁用，因此Return False

from datetime import datetime

now = datetime.now()
current_time = now.strftime("%H:%M")
print("Current Time is ", current_time)

# To Get the Week Number
current_day = datetime.today().weekday()
print("Current Weekday Number is ", current_day)   


data1 = {'setpoint': '366', 'Weekdays': 'True', 'Weekends': 'True', 'starttime': '02:40', 'endtime': '22:40'}
data2 = {'setpoint': '366', 'Weekdays': 'False', 'Weekends': 'True', 'starttime': '02:40', 'endtime': '22:40'}
data3 = {'setpoint': '366', 'Weekdays': 'True', 'Weekends': 'False', 'starttime': '02:40', 'endtime': '03:40'}
data4 = {'setpoint': '366', 'Weekdays': 'False', 'Weekends': 'False', 'starttime': '02:40', 'endtime': '22:40'}



def condition_checker(data,current_time,current_day):
    between_time = data['starttime'] <= current_time <= data['endtime']
    #print("between_time", between_time)

    disabled = data['Weekends'] == False and data['Weekdays'] == False
    print("disabled is", disabled)
    
    weekday_rules = current_day in [0,1,2,3,4]
    #print("weekday_rules", weekday_rules)

    weekend_rules = current_day in [5,6]
    #print("weekend_rules", weekend_rules)
    
    if between_time and not disabled and weekday_rules or between_time and not disabled and weekend_rules:
        return True
    else:
        return False

data1 似乎工作正常：

# True weekend/weekdays and on start/end times 
condition_checker(data1,current_time,current_day)

返回

disabled is False
True

data2 似乎工作正常：

# True on Weekends and start/end times
condition_checker(data2,current_time,current_day)

返回

disabled is False
True

data3 似乎工作正常：

# False on times
condition_checker(data3,current_time,current_day)

返回

disabled is False
False

這是我的邏輯不工作的地方，在disabled數據4不工作時應該是假的

# False on disabled
condition_checker(data4,current_time,current_day)

返回

disabled is False
True

您正在將字符串與函數中的布爾值進行比較。 我會改變字典來保存布爾值True / False像這樣：

data1 = {'setpoint': '366', 'Weekdays': True, 'Weekends': True, 'starttime': '02:40', 'endtime': '22:40'}
data2 = {'setpoint': '366', 'Weekdays': False, 'Weekends': True, 'starttime': '02:40', 'endtime': '22:40'}
data3 = {'setpoint': '366', 'Weekdays': True, 'Weekends': False, 'starttime': '02:40', 'endtime': '03:40'}
data4 = {'setpoint': '366', 'Weekdays': False, 'Weekends': False, 'starttime': '02:40', 'endtime': '22:40'}

或者（不太可取但也有效），您可以更改函數以檢查string值：

def condition_checker(data,current_time,current_day):
    between_time = data['starttime'] <= current_time <= data['endtime']
    disabled = data['Weekends'] == "False" and data['Weekdays'] == "False"
    print("disabled is", disabled)
    
    weekday_rules = current_day in [0,1,2,3,4]
    weekend_rules = current_day in [5,6]
    
    if between_time and not disabled and weekday_rules or between_time and not disabled and weekend_rules:
        return True
    else:
        return False
