【Python】文件读写

本文主要是介绍【Python】文件读写，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一、Python读取txt文件

text_file = "xxx.txt"

with open(text_file) as f:
  lines = f.readlines()
  lines = [line.strip() for line in lines]

print(lines)

二、Python写入txt文件

out_text_file = "xxx.txt"

with open(out_text_file, 'w') as f:
  print("writing to text file", file=f)

三、Python写csv文件

Ref. https://www.geeksforgeeks.org/writing-csv-files-in-python/
csvwriter只有writerow方法，没有writecol。原因应该是逗号分隔是行内分隔。

四、ipynb文件转python

Ref. https://linuxhint.com/convert-jupyter-notebook-python/

pip install jupyter
jupyter nbconvert xxx.ipynb --to python

五、Python读取MATLAB mat文件

from scipy.io import loadmat
annots = loadmat('cars_train_annos.mat')

print(annots.keys())
