利用pandas库, 将numpy的array数据保存成csv格式的文件: import pandas as pd import numpy as np data = pd.read_csv('C:\\abc\\a.csv', header=None) col1 = data.values[:,0] col2 = data.values[:,1]-0.9 for i in range(0, len(col2)): col2[i] = float("%.2f" % col2[i]) co
读取csv文件: def readCsv(): rows=[] with file(r'E:\py\py01\Data\system.csv','rb') as f: reads=csv.reader(f) for i in reads: rows.append(i) print rows return rows写入csv文件: def writer(): with file(r'E:\py\py01\Data\system.csv','wb') as f: writer=csv.writer(
dlgSave := TSaveDialog.Create(nil); dlgSave.filter := 'CSV文件|*.CSV'; dlgSave.DefaultExt := '*.CSV'; dlgSave.filename := '服务.CSV'; if dlgSave.Execute then begin if FileExists(dlgSave.filename) then try ) = IDYES then DeleteFile(PChar(dlgSave.filename)
#coding=utf-8 import os import pandas as pd import glob def hebing(): csv_list = glob.glob('*.csv') print(u'共发现%s个CSV文件'% len(csv_list)) print(u'正在处理............') for i in csv_list: fr = open(i,'r').read() with open('haha.csv','a') as f: f.write(fr)
