基数为10的int（）的文本无效：“63，”

Question

我正在运行以下程序，它会产生以下故障。我认为逻辑是正确的。怎么了

invalid literal for int() with base 10: '63,' 

代码：

for i in range(length):
    k=i+1
    if (sample_text[i]  == "r" and sample_text[k] == "e" ):
        iTemp = i
        iTemp = iTemp + 9 
        var = ""
        finalList = []
        while (sample_text[iTemp] != "]"):
            iTemp = iTemp + 1 
            while (sample_text[iTemp] != "," or sample_text[iTemp] != "]"):
                tempVar = sample_text[iTemp]
                var = var + tempVar
                num = int(var)
                iTemp = iTemp + 1 

Answer 1

假设sample_text[iTemp]等于","。然后是表达式

sample_text[iTemp] != "," or sample_text[iTemp] != "]"

将等于False or True，这等于True，然后输入循环体并将逗号附加到文本中

这里需要的逻辑运算符是and：

sample_text[iTemp] != "," and sample_text[iTemp] != "]"
