reading multiple tabs from excel in different dataframes

Question

I am trying to read multiple tabs in spreadsheet to different dataframes and once all tabs with data are over the program should stop.

For first part I am looking to

Answer 1

Demo:

file name

In [94]: fn = r'D:\temp\.data\test.xlsx'

creating pandas.io.excel.ExcelFile object

In [95]: xl = pd.ExcelFile(fn)

it has sheet_names attribute

In [96]: xl.sheet_names
Out[96]: ['Sheet1', 'aaa']

we can use it for looping through sheets

In [98]: for sh in xl.sheet_names:
    ...:     df = xl.parse(sh)
    ...:     print('Processing: [{}] ...'.format(sh))
    ...:     print(df.head())
    ...:
Processing: [Sheet1] ...
   col1  col2  col3
0    11    12    13
1    21    22    23
2    31    32    33
Processing: [aaa] ...
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

a bit more elegant way is to generate a dictionary of DataFrames:

In [100]: dfs = {sh:xl.parse(sh) for sh in xl.sheet_names}

In [101]: dfs.keys()
Out[101]: dict_keys(['Sheet1', 'aaa'])

In [102]: dfs['Sheet1']
Out[102]:
   col1  col2  col3
0    11    12    13
1    21    22    23
2    31    32    33

In [103]: dfs['aaa']
Out[103]:
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

Answer 2

This will read all sheets and make a dictionary of dataframes:

xl = pd.read_excel('Unique.xlsx', sheet_name=None)

To get specific sheets, you could do:

xl_dict = {}
sheetname_list = ['blah1', 'blah2', 'blah3']
for sheet in sheetname_list:
    xl_dict[sheet] = pd.read_excel('Unique.xlsx', sheet_name=sheet)

or:

xl = pd.read_excel('Unique.xlsx', sheet_name=sheetname_list)
