今天来看看梁总出的练习题哈

转换成下面的二维表效果图(要求：必须要跟效果表一致)

方法1：

小子大神Python：

import xlrd

import xlwt

s = set()

d = {}

a = 0

rs = 0

cs =0

f = xlwt.Workbook()

st = f.add_sheet(r'newcity',cell_overwrite_ok=True)

wb = xlrd.open_workbook(r'E:\excel\city.xlsm')

sh = wb.sheets()[0]

for i in range(1,sh.nrows):

d[sh.cell_value(i,1) sh.cell_value(i,0)]=sh.cell_value(i,2)

d[sh.cell_value(i,0) sh.cell_value(i,1)]=sh.cell_value(i,2)

s.add(sh.cell_value(i,1))

s.add(sh.cell_value(i,0))

for r in s:

rs = 1

cs =0

for c in s:

cs =1

if r c in d:

st.write(cs,rs,d[r c])

else:

st.write(cs,rs,0)

st.write(rs,0,r)

st.write(0,rs,r)

print(d)

print(s)

f.save(r'E:\\excel\\citys.xls')
