1.在python中excel的简单读写操作,推荐使用xlrd(特别是读操作)

2.到http://pypi.python.org/pypi/xlrd 去下载 xlrd库;

3.工程代码如下:

复制代码 代码如下:

import xlrd     

def open_excel(fileName="simple.xls"):    
    try:    
        fileHandler = xlrd.open_workbook(fileName)    
        return fileHandler    
    except Exception, e:    
        print str(e)        

def scan_excel(sheet_name1=u'Sheet1'):    
    handler = open_excel()    
    page = handler.sheet_by_name(sheet_name1)    
    return page    

def trim_cols(index=0):    
    page = scan_excel()    
    col1 = page.col_values(index)    
    col2 = []    

    for item in col1:    
        if item not in col2:    
            col2.append(item)    
    print col1    
    print col2    

def main():    
    trim_cols()    

if __name__ == "__main__":    
    main()    

打印结果:
[1.0, 2.0, 3.0, 4.0, 1.0, 2.0, 3.0, 4.0]
[1.0, 2.0, 3.0, 4.0]
