datetime.datetime'>怎么去掉时分秒

import numpy as np
import pandas as pd
import datetime
from dateutil.parser import parse

data1 = pd.read_csv('result.txt',sep='\t')
data1 = pd.DataFrame(data1)
data1 = np.array(data1)

print(data1[0][3])
data1[0][3] = parse(data1[0][3])
print(type(data1[0][3]))

请采纳

import datetime
import time

# time
print(time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()))
print(time.strftime("%Y-%m-%d", time.localtime()))
print(time.strftime("%H:%M:%S", time.localtime()))
# datetime
print(datetime.datetime.now().strftime("%Y-%m-%d"))
