本文主要是关于pandas的一些基本用法。
#!.../usr/bin/env python

import pandas as pd
import numpy as np
# Test 1
# 创建DataFrame..., df2, df3], axis = 1)
print res
# 合并的同时index重新排序
res = pd.concat([df1, df2, df3], axis = 0, ignore_index..., 默认的join模式为outer, 与pd.concat([df1, df2])是一样的
res = pd.concat([df1, df2], join = 'outer')
print res...res = pd.concat([df1, df2], axis = 1)
print res
# 横向合并, 按照df1的index, 忽略df2不一致的index
res = pd.concat
