ubuntu下打亂txt文件行序（搬運）批量修改文件名

將 train_160309-train.txt按行打亂，每行內容則保持不變，命令：

cd 存放文件的路徑
awk 'BEGIN{ 100000*srand();}{ printf "%s %s\n", rand(), $0}'   train_160309-train.txt |sort -k1n | awk '{gsub($1FS,""); print $0}' 

但這樣處理後只是在屏幕上輸出顯示，如果需要將輸出寫入新的文本train.txt，則在末尾加上 | tee train.txt：

sudo awk 'BEGIN{ 100000*srand();}{ printf "%s %s\n", rand(), $0}'   train_160309-train.txt |sort -k1n | awk '{gsub($1FS,""); print $0}' | tee train.txt

如果不需要在屏幕上輸出顯示，直接將輸出寫入新的文本train.txt，則在末尾將 | tee 換作 > 即可：

sudo awk 'BEGIN{ 100000*srand();}{ printf "%s %s\n", rand(), $0}'   train_160309-train.txt |sort -k1n | awk '{gsub($1FS,""); print $0}' > train.txt

親測可行

批量修改文件名：

#-*- coding: UTF-8 -*-
import os
filenames = os.listdir(os.getcwd())  
for name in filenames:
    print(name)
for num in range(0,len(filenames)):
    if(num<10):
        print()
        print(filenames[num])
        os.rename(filenames[num],'0'+str(num)+'.png')
    else:
        os.rename(filenames[num],str(num)+'.png')

比較兩個csv文件是否相同

import csv

with open("/home/drone/Desktop/test4.csv","r") as csvfile1:
    reader1=csv.reader(csvfile1)
    list1=[row for row in reader1]
with open("/home/drone/Desktop/B8500(544).csv","r") as csvfile2:
    reader2=csv.reader(csvfile2)
    list2=[row for row in reader2]

for i in range(len(list1)):
    for j in range(len(list1[0])):
        if list1[i][j]!=list2[i][j]:
            print(list1[i])
            print(list1[i][j])
            print("error")

寫csv文件

import csv
with open("test.csv","w") as csvfile:#文件生成路徑
     writer=csv.writer(csvfile)
     writer.writerow(["id","w","h"])#寫入一行
     writer.writerows([[0,1,2],[1,2,3]])#寫入多行
