12.13.1 乘法表
法一
from openpyxl.workbook import Workbook
from openpyxl.styles import Font
import sys
import os
os.chdir('.') #记得改变当前工作目录至目的地不然找不到文件
n = int(sys.argv[1])
wb = Workbook()
ws = wb.active
ws.freeze_panes = 'B2' #冻结窗口
f = Font(bold=True)
#将第一行和第一列数字填入并设置格式
for i in range(1,n+1):
ws.cell(row=1,column=i+1).value = i
ws.cell(row=i+1,column=1).value = i
ws.cell(row=1,column=i+1).font = f
ws.cell(row=i+1,column=1).font = f
#遍历剩下单元格将选取对应的数字相乘得到的结果填入
for row in ws.iter_rows(min_row=2, min_col=2, max_row=n+1,max_col=n+1):
for cell in row:
cell.value = int(ws.cell(row=1,column=cell.column).value)\
*int(ws['A'+str(cell.row)].value)
wb.save('121301.xlsx')
print('DONE')
法二
from openpyxl.workbook import Workbook
from openpyxl.styles import Font
import sys
wb = Workbook()
ws = wb.active
ws.freeze_panes = 'B2'
n = int(sys.argv[1])
f = Font(bold=True)
#判断分支对应填入
for row in ws.iter_rows(min_row=1,min_col=1,max_row=n+1,max_col=n+1):
for c in row:
row = c.row
col = c.column
if row == 1 and col == 1:
continue
elif row == 1:
c.value = col - 1
c.font = f
elif col == 1:
c.value = row - 1
c.font = f
else:
c.value = (row-1)*(col-1)
wb.save('12130102.xlsx')
print('DONE')
总结：法二相对较简洁些，法一的思路个人认为比较常规。
12.13.02
from openpyxl import load_workbook
import sys
import os
os.chdir(r'C:\Users\Yuuunoooo\Desktop')
n = int(sys.argv[1])
m = int(sys.argv[2])
wb = load_workbook('sampleChart.xlsx')
ws = wb['Sheet']
for i in range(m):
ws.insert_rows(n)
wb.save('sampleChart2.0.xlsx')
print('DONE')
总结：没有用书上的一些提示。因为查官方字典发现有了Sheet对象的insert_rows(n)直接在第n行插入，于是一切变得不一样。PS：在保存时保存为新的文件这样就可以保留原文件了。
12.13.03 电子表格单元格翻转
法1
from openpyxl import load_workbook
from openpyxl import Workbook
wb = load_workbook('123.xlsx')
ws = wb['Sheet1']
cellList = []
rowList = []
for col in range(1,ws.max_column + 1):
for row in range(1,ws.max_row + 1):
rowList.append(ws.cell(column=col,row=row).value) #将一列数据写入列表rowList
cellList.append(rowList) #将rowList添加到cellList列表
rowList = [] #更新rowList
ws2 = wb.create_sheet('Sheet')
#将数据写入新列表
for x in range(len(cellList)):
for y in range(len(cellList[0])):
ws2.cell(column=y+1,row=x+1).value = cellList[x][y]
wb.remove(ws)
wb.save('new_123.xlsx')
print('DONE')
法2
from openpyxl import load_workbook
wb = load_workbook('123.xlsx')
ws = wb['Sheet1']
cellList = []
maxRow = ws.max_row
maxCol = ws.max_column
for col in ws.iter_cols(min_row=1, max_row=maxRow, max_col=maxCol):
for cell in col:
cellList.append(cell.value)
ws2 = wb.create_sheet('newSheet1')
n = 0
for row in ws2.iter_rows(min_row=1, max_row=maxCol, max_col=maxRow):
for cell in row:
cell.value = cellList[n]
n += 1
#print(cell.value)
wb.remove(ws)
wb.save('new_123.xlsx')
print('DONE')
思路：1.法一是按照书上的提示思路写的，将电子表格中的数据读入一个列表的列表
2.用创建新的Sheet方法写入新数据，这样就不用删除掉原数据再写了。（主要是没找到什么好的方法去删除整个Sheet的数据= =用循环还不如直接创建一个新的）
- 法二的思路是在想尝试用字典方法写一遍后发现的。运用了ws.iter_rows()和ws.iter_cols的有序读取方法。发现非常高效就完成了翻转！可以参考官方文档https://openpyxl.readthedocs.io/en/stable/tutorial.html 了解上述两种方法。
12.13.04 文本文件到电子表格
#文本文件到电子表格
from openpyxl.workbook import Workbook
fileList = ['1.txt','2.txt','3.txt']
wb = Workbook()
ws = wb.active
for i in range(len(fileList)):
file = open(fileList[i], 'r')
lineList = file.readlines()
n = 1
for line in lineList:
ws.cell(column=i+1,row=n).value = line
n += 1
wb.save('123combine.xlsx')
print('DONE')
12.13.05 电子表格到文本文件
#电子表格到文本文件
from openpyxl import load_workbook
wb = load_workbook('123combine.xlsx')
ws = wb.active
for col in range(1,ws.max_column+1):
file = open(str(col) + '.txt','w')
print('writing data to %s ...' % (str(col) + '.txt'))
for row in range(1,ws.max_row+1):
line = ws.cell(row=row,column=col).value
if line != None:
file.write(str(line)+'\n')
else:
continue
file.close()
s
print('DONE')
注意：write方法不加str后有些数据会写不进去。暂时还不知道什么原因。各位大神如果知道可以教教我www
以上。如果有什么问题欢迎找我一起探讨:)
