Python：为输出CSV文件添加处理时间

下面的代码创建一个熊猫数据帧并将其输出到csv文件中。它还为处理时间计时。如何将处理时间添加到csv文件

谢谢你抽出时间

import pandas as pd
import csv
import time
def procedure():
    time.sleep(0)
t0 = time.clock()
y=pd.DataFrame({'one':[1,2,3,4],'two':[3,5,7,5],'three':[2,3,4,9],'four':[4,3,1,0],})
y.to_csv('temp1.csv')
procedure()
print (time.clock()-t0)

---

以追加模式打开文件以将时间添加到结束：

...
procedure()
elapsed = time.clock()-t0
with open('temp1.csv', 'a') as f:
    f.write(str(elapsed))

...
procedure()
elapsed = time.clock()-t0
with open('temp1.csv', 'a') as f:
    f.write(str(elapsed))

要获得处理时间，您可以使用如下代码：

import pandas as pd
import csv
import time
def procedure():
    time.sleep(0)
start_time = time.time()
y=pd.DataFrame({'one':[1,2,3,4],'two':[3,5,7,5],'three':[2,3,4,9],'four':[4,3,1,0],})
y.to_csv('temp1.csv')
procedure()
finish_time = time.time() - start_time
print (finish_time)

要获得处理时间，您可以使用如下代码：

import pandas as pd
import csv
import time
def procedure():
    time.sleep(0)
start_time = time.time()
y=pd.DataFrame({'one':[1,2,3,4],'two':[3,5,7,5],'three':[2,3,4,9],'four':[4,3,1,0],})
y.to_csv('temp1.csv')
procedure()
finish_time = time.time() - start_time
print (finish_time)

您的缩进已关闭：

import pandas as pd
import csv
import time

def procedure():
    time.sleep(0)
    y=pd.DataFrame({'one':[1,2,3,4],'two':[3,5,7,5],'three':[2,3,4,9],'four':[4,3,1,0],})
    y.to_csv('temp1.csv')

start_time = time.time()    
procedure()
finish_time = time.time() - start_time
print (finish_time)

import pandas as pd

def procedure():
    time.sleep(0)
    y=pd.DataFrame({'one':[1,2,3,4],'two':[3,5,7,5],'three':[2,3,4,9],'four':[4,3,1,0],})
    y.to_csv('temp1.csv')

start_time = time.time()    
procedure()
finish_time = time.time() - start_time
print (finish_time)

美丽的。谢谢美丽的。谢谢你在windows机器上吗？你在windows机器上吗？
