[英]How do I iterate through a dataframe's columns and then run the describe() function on each of these columns?
What I have tried so far is to iterate through the dataframe columns and then use the control variable in the df.<columnName>.describe()
function, but this doesn't seem to work...到目前为止我尝试过的是遍历数据框列,然后在
df.<columnName>.describe()
函数中使用控制变量,但这似乎不起作用......
for (columnName, columnData) in df.iteritems():
print('Column Name: {}'.format(columnName))
column_stats = df.columnName.describe()
This is the output :这是输出:
attr__ return object. attr__ 返回对象。 getattribute (self, name) AttributeError: 'DataFrame' object has no attribute 'columnName'
getattribute (self, name) AttributeError: 'DataFrame' 对象没有属性 'columnName'
Can someone help me with this rather trivial doubt ...有人可以帮我解决这个相当微不足道的疑问吗...
Try it:尝试一下:
for columnName, columnData in df.iteritems():
print('Column Name: {}'.format(columnName))
column_stats = df[columnName].describe()
df.columnName is searching for a Column Name ColumnName not the value of your variable df.columnName 正在搜索列名 ColumnName 不是变量的值
