pandas 将多个CSV文件（具有相同的结构）读取并合并到一个DF中
示例
import os
import glob
import pandas as pd
def get_merged_csv(flist, **kwargs):
return pd.concat([pd.read_csv(f, **kwargs) for f in flist], ignore_index=True)
path = 'C:/Users/csvfiles'
fmask = os.path.join(path, '*mask*.csv')
df = get_merged_csv(glob.glob(fmask), index_col=None, usecols=['col1', 'col3'])
print(df.head())如果要水平合并CSV文件（添加列），请axis=1在调用函数时使用：pd.concat()
def merged_csv_horizontally(flist, **kwargs):
return pd.concat([pd.read_csv(f, **kwargs) for f in flist], axis=1)
