使用python對excel文件操作保存后（save函數）文件被破壞解決辦法

今日進行了利用python對excel的文本操作，這方面的文章網上已經有很多了，在此不再贅述，只要使用幾個庫就行了：

import xlrd
import xlwt
from datetime import date,datetime
from xlutils.copy import copy

然后使用其中的函數即可對excel文件進行讀、寫、修改、保存等諸多功能，十分方便。
但是今日在利用“from xlutils.copy import copy”保存excel文件后，遇到了文件無法再次打開的問題，並報錯。但是重新運行python代碼確可以讀取並再次操作其中的數據，因此文件肯定還是好的，一定是格式出現了錯誤，后來經過調試及搜索，果然是格式的問題，save函數只能將excel文件保存成.xls文件，而代碼卻將其保存成.xlsx文件，因此格式不對，無法打開，將其修改后成功打開，並且前期對excel內容的操作也都十分成功，數據已經成功寫入，以下附上對excel的操作代碼：

import xlrd

from datetime import date,datetime
from xlutils.copy import copy

def read_excel(name,user_name):     #輸入文件名和用戶名
    # 打開文件
    workbook = xlrd.open_workbook(name)
    # 獲取所有sheet
    #print (workbook.sheet_names()) # ['sheet1']
    sheet1_name = workbook.sheet_names()[0]

    # 根據sheet索引或者名稱獲取sheet內容,read the content of the sheet
    sheet1 = workbook.sheet_by_index(0) # sheet索引從0開始
    sheet1 = workbook.sheet_by_name('sheet1')  #通過名稱來找到sheet2

    # sheet的名稱,行數,列數
    print (sheet1.name,sheet1.nrows,sheet1.ncols)

    # 獲取整行和整列的值,數組.
    rows = sheet1.row_values(0) # 獲取第0行內容
    cols = sheet1.col_values(2) # 獲取第3列內容
    #print ((rows))
    #print (cols)

    # 獲取單元格內容
    #print (sheet1.cell(1,1).value)
    #print (sheet1.cell_value(1,1))
    #print (sheet1.row(1)[1].value)
    
    # 獲取單元格內容的數據類型
    #print (sheet1.cell(0,1).ctype)
    for i in range(sheet1.nrows):
    	if i < sheet1.nrows:
    		if sheet1.cell(i,0).value == user_name:
    			game_times = sheet1.cell(i,1).value
    			min_times = sheet1.cell(i,2).value
    			total_times = sheet1.cell(i,3).value
    			have_user = 1
    			break
    		else:
    			have_user = 0
    			game_times = 0
    			min_times = 0
    			total_times = 0
    if have_user == 0:
    	wb = copy(workbook)
    	ws = wb.get_sheet(0)
    	style = xlwt.easyxf('font:height 240, color-index red, bold on;align: wrap on, vert centre, horiz center')
    	ws.write(sheet1.nrows, 0, user_name, style)
    	ws.write(sheet1.nrows, 1, str(game_times), style)
    	ws.write(sheet1.nrows, 2, str(min_times), style)
    	ws.write(sheet1.nrows, 3, str(total_times), style)
    	wb.save(r'new_excel.xlsx')
    return have_user,game_times,min_times,total_times




#save the game result to the docunments
def save_geme(game_times,min_times,total_times,times):       #"times" are this round of games' times, and this function needs this(times) to update the old record
	if game_times == 0 or times < min_times:
		min_times = times
	total_times = total_times + times
	game_times += 1
	#write this record to the document
	sheet1 = read_excel('game.xlsx')
	sheet1.cell(1,0).value = game_times
	sheet1.cell(1,1).value = min_times
	sheet1.cell(1,2).value = total_times
	#sheet1 = workbook.sheet_by_name('sheet1')
	#workbook.write('A1',game_times)
	#workbook.write('B1',min_times)
	#workbook.write('C1',total_times) #暫時還沒考慮是否需要關閉文件,最好做一個輸出
	print(sheet1.cell(0,0).value,":",sheet1.cell(1,0).value)
	print(sheet1.cell(0,1).value,":",sheet1.cell(1,1).value)
	print(sheet1.cell(0,2).value,":",sheet1.cell(1,2).value)

if __name__ == '__main__':
	
	# start the real game
	print("請輸入您的游戲用戶名:")
	user_name = input()
	[have_user,game_times,min_times,total_times] = read_excel('game.xlsx',user_name)    #read the xlsx file
	if int(game_times) != 0:
		print(type(total_times))
		avg_times = float(total_times) / int(game_times)	
	else:
		avg_times = 0
	print('{0}已經玩了{1}次,最少是{2}輪猜出答案,平均{3}輪猜出答案'.format(user_name,int(game_times),int(min_times),total_times))

	#start this round game
	times = 0          #this round game' times

運行后：
就會多出一個.xlsx文件，改成.xls文件就可以啦。並且寫入也成功了：。
