Question

我是新来的，这可能是一个非常愚蠢的问题，但我刚开始学习python并且在jupyter笔记本中遇到麻烦。例如：

def greatest(list):
    biggest = 0
    for i in list:
        if e > biggest:
            biggest = i 
    return biggest

然后我尝试：

print greatest([4,23,1])

错误消息显示语法错误：语句无效，同时指向“最大”区域之间的区域。和（[4,23,1]）在打印命令中。我一直试图打印类似的东西，总是有一个数字列表。我该怎么办？

Answer 1

请参阅下面的代码。我纠正了一些事情，我已将其包含在代码注释中

def greatest(numbers):  # Renamed list to numbers, since list is reserved
    biggest = 0
    for i in numbers:
        if i > biggest:   # e here should be i
            biggest = i 
    return biggest 

print(greatest([4,23,1]))  # We need brackets around what we are printing since this is py3

Answer 2

您只需使用max(list)作为：

 l =  [4,23,1]
 print max(l)

<强>输出：

Jupyter笔记本 - 打印时列表无效[list]
