Python Pandas基于时间戳合并两个CSV

Question

有人可以根据时间戳给我一个如何合并两个CSV文件的提示吗？ Concat有效，但我还需要根据 一个 单个戳记DateTime来组织数据。在下面的shell输出片段中，两个DateTime列都是可见的。谢谢

import pandas as pd
import numpy as np
import datetime

WUdata = pd.read_csv('C:\\Users\\bbartling\\Documents\\Python\\test_SP 
data\\3rd GoRound k Nearest\\WB data\\WU\\WUdata.csv')

print(WUdata.describe())
print(WUdata.shape)
print(WUdata.columns)
print(WUdata.info())

kWdata = pd.read_csv('C:\\Users\\bbartling\\Documents\\Python\\test_SP 
data\\3rd GoRound k Nearest\\WB data\\WU\\kWdata.csv')

print(kWdata.describe())
print(kWdata.shape)
print(kWdata.columns)
print(kWdata.info())

merged = pd.concat([WUdata, kWdata], axis=1)

print(merged)
