缩进错误：unindent不匹配任何外部缩进级别

Question

我似乎无法弄清楚这里发生了什么。当我编译我得到的不符合错误。

它给了我关于缩进不匹配就行了误差bgB = 0;

def calcBG(ftemp): 
"This calculates the color value for the background" 
variance = ftemp - justRight; # Calculate the variance 
adj = calcColorAdj(variance); # Scale it to 8 bit int 
bgList = [0,0,0]    # initialize the color array 
if(variance < 0):   
    bgR = 0;     # too cold, no red   bgB = adj;     # green and blue slide equally with adj   bgG = 255 - adj;  elif(variance == 0):   # perfect, all on green   bgR = 0;   bgB = 0;   bgG = 255;  elif(variance > 0):    # too hot - no blue 
    bgB = 0; 
    bgR = adj;     # red and green slide equally with Adj 
    bgG = 255 - adj; 

所以更新什么@Downshift建议的代码，并增加了一些elifs后，我得到了同样的事情 def calcBG(ftemp): "This calculates the color value for the background" variance = ftemp - justRight; # Calculate the variance adj = calcColorAdj(variance); # Scale it to 8 bit int bgList = [0,0,0] # initialize the color array if(variance < 0):
bgR = 0; # too cold, no red
bgB = adj; # green and blue slide equally with adj
bgG = 255 - adj;
elif(variance == 0): # perfect, all on green
bgR = 0;
bgB = 0;
bgG = 255;
elif(variance > 0): # too hot - no blue bgB = 0; bgR = adj; # red and green slide equally with Adj bgG = 255 - adj;

另外：如果有人可以指出/向我解释我的失败，那就太好了。因为我似乎无法在第二部分找到我的问题。这与第一个问题相同。

正如解释器告诉你缩进级别不一致。一定的方法定义和if报表第一行后缩进，没有比固定缩进其他更改您的代码：

def calcBG(ftemp): 
    """This calculates the color value for the background""" 
    variance = ftemp - justRight; # Calculate the variance 
    adj = calcColorAdj(variance); # Scale it to 8 bit int 
    bgList = [0,0,0]    # initialize the color array 
    if(variance < 0):   
     bgR = 0;     # too cold, no red   bgB = adj;     # green and blue slide equally with adj   bgG = 255 - adj;  elif(variance == 0):   # perfect, all on green   bgR = 0;   bgB = 0;   bgG = 255;  elif(variance > 0):    # too hot - no blue 
     bgB = 0; 
     bgR = adj;     # red and green slide equally with Adj 
     bgG = 255 - adj;
