以上两个列表可以通过使用list(zip())函数进行合并。现在,通过调用pd.DataFrame()函数创建pandasDataFrame。 # Python program to demonstrate creating# pandas Datadaframe from lists using zip.importpandasaspd# List1Name=['tom','krish','nick','juli']# List2Age=[25,30,26,22]# get the list of tu...

Dropping one or more entries from an axis is easy if you already hava an index array or list without those entries. As that can requier a bit of munging(操作) and set logic. The drop method will return a new object with the indecated value or values deleted from an axis: obj = pd...

Hierarchical axis indexing provides an intuitive way of working with high-dimensional data in a lower-dimensional data structure; Time series-functionality: date range generation and frequency conversion, moving window statistics, moving window linear regressions, date shifting and lagging. Even create dom...
An important method on pandas objects is reindex, which means to create a new object with the data conformed to a new index. Consider an example: obj=pd.Series([4.5,7.2,-5.3,3.6],index=['d','b','a','c']) obj 1. 2. d 4.5 ...
Create an array. Parameters --- data : Sequence of objectsThe scalars inside `data` should be instances of thescalar type for `dtype`. It's expected that `data`represents a 1-dimensional array of data.When `data` is an Index or Series, the underlying arraywill be extracted from `data`...
