准备把df文件按条件写入csv2的,但是写出来是空文件。所以我就按以下代码打印了一下发现只有字段,没有记录。
哪位老兄遇到过呢?还望指教一二
import pandas as pd import numpy as np import plotly.plotly as py import plotly.tools as tls import plotly.graph_objs as go import json import csv from collections import defaultdict tls.set_credentials_file(username='**', api_key='**') f1 = open('E://ss.csv','r') df = pd.read_csv(f1,dtype = {'***':str}) wf=open('csv2.csv','w') write = csv.writer(wf) for row in df: print(row) # if row[0] == '6': # write.writerow(row) f1.close()
