# "Steep" means the slope of the line is greater than 45 degrees or # less than -45 degrees: # Check for the special case where the start and end points are # certain neighbors, which this function doesn't handle correctly, # and return a hard coded list instead: if (x1 == x2 ...
Do a tiny bit at a time throughout the day and mark down what you need to work on most. 常见逻辑运算符及术语:andornot!= (not equal)== (equal)>= (greater-than-equal)<= (less-than-equal)TrueFalse你可以自己将上述运算符来组合测试。例如not False,True or False,not (False or True)...

So before runtime, array is re-assigned to the list [2, 8, 22], and since out of 1, 8 and 15, only the count of 8 is greater than 0, the generator only yields 8. The differences in the output of g1 and g2 in the second part is due the way variables array_1 and array_...
