在Python中，如何判断一组M个条件中的N个条件是否为真？

condition1 = True
condition2 = True
condition3 = False

if condition1 and condition2 and condition3:
    print("所有条件都为真")
else:
    print("至少有一个条件为假")

condition1 = False
condition2 = False
condition3 = True

if condition1 or condition2 or condition3:
    print("至少有一个条件为真")
else:
    print("所有条件都为假")

condition1 = False

if not condition1:
    print("条件为假")
else:
    print("条件为真")
