对Python 2.7 pandas 中的read_excel详解

import pandas as pd

df = pd.read_excel('log.xls')

df = pd.read_excel('log.xls', sheetname=1)

df.dtypes

Member   object
Unnamed: 1 float64
Unnamed: 2 float64
Unnamed: 3 float64
Unnamed: 4 float64
Unnamed: 5 float64
家内外活动类型  object
Unnamed: 7  object
activity  object
dtype: object

new_df = df.drop_duplicates(subset='Member', keep='last')

out = pd.ExcelWriter('output.xls')
new_df.to_excel(out)
out.save()

#coding=utf-8
import pandas as pd
 
# 读入excel文件中的第2个表
df = pd.read_excel('log.xls', sheetname=1)
# 查看表的数据类型
print df.dtypes
# 查看Member列的数据
print df['Member']
 
'''
# 新建一列，每一行的值是Member列和activity列相同行值的和
for i in df.index:
 df['activity_2'][i] = df['Member'][i] + df['activity'][i]
'''
 
# 根据Member字段去除掉多余的行，并且保留相同行的最后一行数据
new_df = df.drop_duplicates(subset='Member', keep='last')
# 导出结果
out = pd.ExcelWriter('output.xls')
new_df.to_excel(out)
out.save()
