数据分析 Python读取txt文本数据，写进excel中

因为项目需要，需要统计训练的loss和acc，写进excel中，用手统计太累了。

方法：读取文档后，采用split分割出数据，然后用列表保存，再将列表内容写进excel中。

txt文本内容如下所示：

直接上代码，代码的value_title 需要自己手动更改：

# coding=UTF-8

import xlrd

import xlwt

from xlutils.copy import copy

import numpy as np

def write_excel_xls(path, sheet_name, value):

index = len(value) # 获取需要写入数据的行数

workbook = xlwt.Workbook() # 新建一个工作簿

sheet = workbook.add_sheet(sheet_name) # 在工作簿中新建一个表格

for i in range(0, index):

for j in range(0, len(value[i])):

sheet.write(i, j, value[i][j]) # 像表格中写入数据（对应的行和列）

workbook.save(path) # 保存工作簿

print("xls格式表格写入数据成功！")

def write_excel_xls_append(path, value,j):

index = len(value) # 获取需要写入数据的行数

print(index)

workbook = xlrd.open_workbook(path) # 打开工作簿

sheets = workbook.sheet_names() # 获取工作簿中的所有表格

worksheet = workbook.sheet_by_name(sheets[0]) # 获取工作簿中所有表格中的的第一个表格

# rows_old = worksheet.nrows # 获取表格中已存在的数据的行数

rows_old = 1 # 获取表格中已存在的数据的行数

new_workbook = copy(workbook) # 将xlrd对象拷贝转化为xlwt对象

new_worksheet = new_workbook.get_sheet(0) # 获取转化后工作簿中的第一个表格

for i in range(0, index):

print(i)

print(value[i])

new_worksheet.write(i+rows_old, j, str(value[i])) # 追加写入数据，注意是从i+rows_old行开始写入

new_workbook.save(path) # 保存工作簿

print("xls格式表格【追加】写入数据成功！")

def read_excel_xls(path):

workbook = xlrd.open_workbook(path) # 打开工作簿

sheets = workbook.sheet_names() # 获取工作簿中的所有表格

worksheet = workbook.sheet_by_name(sheets[0]) # 获取工作簿中所有表格中的的第一个表格

for i in range(0, worksheet.nrows):

for j in range(0, worksheet.ncols):

print(worksheet.cell_value(i, j), "\t", end="") # 逐行逐列读取数据

print()

if __name__ == "__main__":

file = open("MyNet.txt")

Train_ET = []

Train_TC = []

Train_WT = []

Valid_ET = []

Valid_TC = []

Valid_WT = []

Train_loss = []

Valid_loss = []

for idx,line in enumerate(file.readlines()):

if idx%2 != 0:

Train_ET.append(line.split()[1])

Train_TC.append(line.split()[3])

Train_WT.append(line.split()[5])

Valid_ET.append(line.split()[7])

Valid_TC.append(line.split()[9])

Valid_WT.append(line.split()[11])

else:

Train_loss.append(line.split()[2])

Valid_loss.append(line.split()[4])

# print(Train_ET)

# print(Train_TC)

# print(Train_WT)

# print(Valid_ET)

# print(Valid_TC)

# print(Valid_WT)

# print(Train_loss)

# print(Valid_loss)

book_name_xls = '测试值.xls'

sheet_name_xls = '测试值表'

value_title = [["Train_ET", "Train_TC", "Train_WT", "Valid_ET", "Valid_TC","Valid_WT","Train_loss","Valid_loss",],]

write_excel_xls(book_name_xls, sheet_name_xls, value_title)

write_excel_xls_append(book_name_xls, Train_ET, 0)

write_excel_xls_append(book_name_xls, Train_TC, 1)

write_excel_xls_append(book_name_xls, Train_WT, 2)

write_excel_xls_append(book_name_xls, Valid_ET, 3)

write_excel_xls_append(book_name_xls, Valid_TC, 4)

write_excel_xls_append(book_name_xls, Valid_WT, 5)

write_excel_xls_append(book_name_xls, Train_loss, 6)

write_excel_xls_append(book_name_xls, Valid_loss, 7)

 最后生成的结果，很完美。
