1. 将txt文件转换成excel格式，文件格式为：

2,4,"ON",4
0,0,0,1,0,0,2,0,30,3,0,30,4,1,60,5,0,60,6,0,30,7,0,30,8,0,0,9,0,0,10,0,0,11,0,0,12,0,0,13,0,0,14,0,0,15,0,0,16,0,0,17,0,0,18,0,0,19,0,0,20,0,0,21,0,0,22,0,0,23,0,0,24,0,0,25,0,0,26,0,0,27,0,0,28,0,0,29,0,0,30,0,0,31,0,0,32,0,0,33,0,0,34,0,0,35,0,0,36,0,0,37,0,0,38,0,0,39,0,0,40,0,0,41,0,0,42,0,0,43,0,0,44,0,0,45,0,0

需求为行与行之间用换行符分开，列于列之间用逗号分来，代码如下：

import xlwt
wb = xlwt.Workbook(encoding='utf-8')
ws = wb.add_sheet( 'Sheet1') #sheet页第一页
 
f = open('C:\\work\\psycology\\Samples\\fd72.1.txt', encoding='gbk') #.py文件和TestCase.txt同一目录，第一个参数是路径
 
row_excel = 0 #行
 
for line in f:
    line = line.strip('\n') #去掉换行符
    line = line.split(',') #每一行以"，"分隔
 
    print(line) #测试
 
    col_excel = 0 #列
    len_line = len(line)
    for j in range(len_line):
        print(line[j]) #测试
        ws.write(row_excel, col_excel, line[j])
        col_excel += 1
        wb.save('C:\\work\\psycology\\Samples\\fd72.1.xls') #输出在同一目录
 
    row_excel += 1
 
f.close

出现的报错为：PermissionError: [Errno 13] Permission denied

解决方案为：

1.检查对应路径下的文件是否存在，且被占用。如果文件不存在，就找到对应文件即可；如果文件存在，被占用，将占用程序暂时关闭。

2.修改cmd的权限，以管理员身份运行。

3.检查是否是打开了文件夹。

这里，关掉文件夹重新跑一次即可

2. 数出excel中一共有多少行

首先将xls保存成xlsx格式

from openpyxl import load_workbook
wb = load_workbook(filename=r'C:/work/psycology/Samples/fd72.1.xlsx')  ##读取路径
ws = wb.get_sheet_by_name("Sheet1")  ##读取名字为Sheet1的sheet表
num = 1
while 1:
    cell = ws.cell(row=num, column=1).value
    if cell:
        num = num +1
    else:
        print(num-1)
        break
