统计总收入和每一年的收入情况，代码应该如何写呢？

------

计算总收入的代码我是这样写的

import csv
import numpy as np
with open('incoming.csv') as csv_file:
	row = csv.reader(csv_file,delimiter=',')
	next(row)
	income = []
	for r in row:
#		print(r[1])
		income.append(float(r[1]))
print(np.sum(income))
复制代码

那就以年为过滤条件

总收入有了，每一年的收入应该怎么写?

ivor

你的第一列数据应该多了一个逗号,

import pandas as pd
df = pd.read_csv('incoming.csv',parse_dates=['提现时间'],encoding='utf-8')
print("总收入：%d,2020年收入：%s" % (df['提现金额'].sum(),df[df['提现时间'].dt.year == 2020]['提现金额'].sum()))
