动态读取csv文件python pandas [英] Dynamically read csv files python pandas

问题描述

我想在for循环中迭代地从一组csv文件中读取数据. CSV文件的名称为(1.csv，2.csv等)

I would like to iteratively read data from a set of csv files in a for loop. The csv files are named (1.csv, 2.csv and so on)

读取数据的常规方法是

data = pd.read_csv('1.csv')

请问有人使用for循环时如何用i替换1.

Please can someone suggest how to replace 1 by i when using a for loop.

我尝试了data = pd.read_csv(i+'.csv')和data = pd.read_csv(i'.csv')，但是它们不起作用.

I tried data = pd.read_csv(i+'.csv') and data = pd.read_csv(i'.csv') but they did not work.

推荐答案

使用百分比格式

 pd.read_csv('%d.csv' % i)

或format

 pd.read_csv('{0}.csv'.format(i))
