*Numbers(数字)*String(字符串)*List(列表)*Tuple(元组)*Dictionary(字典) 三、 Python数字(Number) Python数字类型用于存储数值数值类型是不允许改变的,这就意味着如果改变数字类型的值,将重新分配内存空间 代码语言:javascript 代码运行次数:0 运行 AI代码解释 var1=10var2=20 也可以使用del语句删除一些数字对象...

a5 = ['Aa', 'Bb', 'Cc'] for v in a5: print v这会依次将 v 设置为列表 a5 的每个元素。可能会定义如下所示的函数:def myfunc(p1, p2): "Function documentation: add two numbers" print p1, p2 return p1 + p2函数也许返回值,也许不返回值。可以使用以下代码调用该函数:...

Here, the ages list has three items. List Items of Different Types Python lists are very flexible. We can also store data of different data types in a list. For example, # a list containing strings, numbers and another list student = ['Jack', 32, 'Computer Science', [2, 4]] print...

它的功能是:Row numbers to use as the column names, and the start of the data. 也就是,它是把某一行作为列名,并且,这一行是数据开始的行。我们测试一下。刚才我们在a.csv文件中只写了两行数据,为了方便测试,我们写上5行数据(大部分数据可以复制粘贴)。 dataframe=pd.read_csv("a.csv",header=1)...
