Python 中pandas.read_excel详细介绍
#coding:utf-8 import pandas as pd import numpy as np filefullpath = r"/home/geeklee/temp/all_gov_file/pol_gov_mon/downloads/1.xls" #filefullpath = r"/home/geeklee/temp/all_gov_file/pol_gov_mon/downloads/26368f3a-ea03-46b9-8033-73615ed07816.xls" df = pd.read_excel(filefullpath,skiprows=[0]) #df = pd.read_excel(filefullpath, sheetname=[0,2],skiprows=[0]) #sheetname指定为读取几个sheet,sheet数目从0开始 #如果sheetname=[0,2],那代表读取第0页和第2页的sheet #skiprows=[0]代表读取跳过的行数第0行,不写代表不跳过标题 #df = pd.read_excel(filefullpath, sheetname=None ,skiprows=[0]) print df print type(df) #若果有多页,type(df)就为<type 'dict'> #如果就一页,type(df)就为<class 'pandas.core.frame.DataFrame'> #{0:dataframe,1:dataframe,2:dataframe}
pandas.read_excel(io, sheetname=0, header=0, skiprows=None, skip_footer=0, index_col=None, names=None, parse_cols=None, parse_dates=False, date_parser=None, na_values=None, thousands=None, convert_float=True, has_index_names=None, converters=None, engine=None, squeeze=False, **kwds)
Read an Excel table into a pandas DataFrame
参数解析:
io : string, path object (pathlib.Path or py._path.local.LocalPath), file-like object, pandas ExcelFile, or xlrd workbook. The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. For instance, a local file could be file://localhost/path/to/workbook.xlsx sheetname : string, int, mixed list of strings/ints, or None, default 0 Strings are used for sheet names, Integers are used in zero-indexed sheet positions. Lists of strings/integers are used to request multiple sheets. Specify None to get all sheets. str|int -> DataFrame is returned. list|None -> Dict of DataFrames is returned, with keys representing sheets. Available Cases Defaults to 0 -> 1st sheet as a DataFrame 1 -> 2nd sheet as a DataFrame “Sheet1” -> 1st sheet as a DataFrame [0,1,”Sheet5”] -> 1st, 2nd & 5th sheet as a dictionary of DataFrames None -> All sheets as a dictionary of DataFrames header : int, list of ints, default 0 Row (0-indexed) to use for the column labels of the parsed DataFrame. If a list of integers is passed those row positions will be combined into a MultiIndex skiprows : list-like Rows to skip at the beginning (0-indexed) skip_footer : int, default 0 Rows at the end to skip (0-indexed) index_col : int, list of ints, default None Column (0-indexed) to use as the row labels of the DataFrame. Pass None if there is no such column. If a list is passed, those columns will be combined into a MultiIndex names : array-like, default None List of column names to use. If file contains no header row, then you should explicitly pass header=None converters : dict, default None Dict of functions for converting values in certain columns. Keys can either be integers or column labels, values are functions that take one input argument, the Excel cell content, and return the transformed content. parse_cols : int or list, default None If None then parse all columns, If int then indicates last column to be parsed If list of ints then indicates list of column numbers to be parsed If string then indicates comma separated list of column names and column ranges (e.g. “A:E” or “A,C,E:F”) squeeze : boolean, default False If the parsed data only contains one column then return a Series na_values : list-like, default None List of additional strings to recognize as NA/NaN thousands : str, default None Thousands separator for parsing string columns to numeric. Note that this parameter is only necessary for columns stored as TEXT in Excel, any numeric columns will automatically be parsed, regardless of display format. keep_default_na : bool, default True If na_values are specified and keep_default_na is False the default NaN values are overridden, otherwise they're appended to verbose : boolean, default False Indicate number of NA values placed in non-numeric columns engine: string, default None If io is not a buffer or path, this must be set to identify io. Acceptable values are None or xlrd convert_float : boolean, default True convert integral floats to int (i.e., 1.0 –> 1). If False, all numeric data will be read in as floats: Excel stores all numbers as floats internally has_index_names : boolean, default None DEPRECATED: for version 0.17+ index names will be automatically inferred based on index_col. To read Excel output from 0.16.2 and prior that had saved index names, use True.
return返回的结果
parsed : DataFrame or Dict of DataFrames DataFrame from the passed in Excel file. See notes in sheetname argument for more information on when a Dict of Dataframes is returned.
