Python编程小结 | 易学教程

为了方便以后查找，记录下平时用到的一些常用方法：

功能：比较两个TXT文件每行的指定位置

import os 
import time

def compute_ap(input,output):
    with open(input,'r') as f_in:
         len_f = len(f_in.readlines())
         print("compute_ap len_f:",len_f)


    with open(input,'r+') as f_in:
        line_1 = f_in.readlines()
        with open(output,'r+') as f_out:
             line_2 = f_out.readlines()
             for row in range(len_f-1):
                 line_1_data = line_1[row].strip('\r\n').split(',')
                 line_2_data = line_1[row].strip('\r\n').split(',')

                 if(abs(float(line_1_data[-2])-float(line_2_data[-1]))):
                     count_temp =count_temp + 1

    f_in.close()
    f_out.close()

功能：读取txt文件，每次一条放入指定txt文件，并执行推理

import os,time
import ac_inference

def extract_line_txt(input_path):
    with open(input_path,'r') as f:
         len_lines = len(f.readlines())
         
    with open(input_path,'r') as f:
         line = f.readlines()
         for row in range(len_lines-1):
             datatxt=[]
             line_data = line[row].strip('\r\n').split(',')
             datatxt.append(line_data[0])
             datatxt.append(line_data[1])
             datatxt.append(line_data[2])
             datatxt.append(line_data[3])
             input_data = ac_inference.test_input_data(datatxt)
             ac_inference.inference(input_data)

     f.close()

功能：读取excel文件，每次一条放入指定txt文件，并执行推理

import xlrd,xlwt,random
import os,time
import ac_inference

#把时间8:30转换成8.5
def transformtime(timestr):
    timelst = timestr.split(":")
    time = int(timelst[0]+int(timelst[1])/60
    return str(time)

def extract_line_xls(filepath):
    wb=xlrd.open_workbook(filepath)
    table=wb.sheet_by_index(0)
    rowsnum = table.nrows-1

    for row in range(rowsnum):
        datatxt=[]
        data=table.row_values(row+1)
        print('extract_line_data[0]:",data[0])
        datatxt.append(transformtime(data[1])
        datatxt.append(data[2])

        print('datatxt:',datatxt)
        input_data=ac_inference.test_input_data(datatxt)
        ac_inference.inference(input_data)input_path =os.path.join(os.getcwd(),'ac_data_input.txt')output_path = os.path.join(os.getcwd(),'ac_output.txt')
