需要比较来自两个不同工作簿的测试用例，如果它们匹配，则将同一行其他列中的结果比较到新工作簿中

Question

我在编写这个东西时卡住了。我有两个 excel 工作簿，它们包含类似 sheets.These sheet 的测试用例，其中一个可能比另一个有更多的测试用例。我正在尝试将不同列中可用的匹配测试用例的结果取出到新文件（最好是excel）。接下来我必须列出其他 sheet 中不存在的测试用例。

import xlrd
import xlwt
m=-1
new=[]
#hard coding of default values
WB1= xlrd.open_workbook("WB1.xls")
WB2= xlrd.open_workbook("WB2.xls")
wb_output = xlwt.Workbook()
ws = wb_output.add_sheet('Comparison_sheet')
WB1_Sheet= WB1.sheet_by_index(1)
WB2_Sheet= WB2.sheet_by_index(1)
if WB1_Sheet.nrows > WB2_Sheet.nrows:
    Last_row=WB2_Sheet.nrows
else:
    Last_row=WB1_Sheet.nrows

if WB1_Sheet.ncols > WB2_Sheet.ncols:
    Last_Column=WB2_Sheet.ncols
else:
    Last_Column=WB1_Sheet.ncols
for x in range(24,Last_row):
    for counter in range(0,30):
        #checking matching test cases in next 20 test cases 
        y=x+counter
        if x>Last_row or y>Last_row:
            y=y-counter
            break;
        if WB2_Sheet.cell_value(x,0) == WB1_Sheet.cell_value(y,0):
            found=1;
            m+=1
            ws.write(m, 0,(str(x +1)))
            ws.write(m, 1,(str(WB1_Sheet.cell_value(x,0)) + "\n" +str(WB2_Sheet.cell_value(y,0))))
            ws.write(m, 2,(str(WB2_Sheet.cell_value(x,3))))
            ws.write(m, 3,(str(WB1_Sheet.cell_value(y,3))))
        if WB2_Sheet.cell_value(x,0) != WB1_Sheet.cell_value(y,0):
            break
first_match_offset=0
for x in range(m,Last_row):
    for counter in range(0,30):
            #checking matching test cases in next 20 test cases 
            #they are sorted such that the test case may appear in next 50 lines or they are not present
            y=x+counter
            if x>Last_row or y>Last_row:
                y=y-counter
                break;
    if WB2_Sheet.cell_value(x,0) == WB1_Sheet.cell_value(y,0):
        first_match_offset = y-m
print first_match_offset
wb_output.save("result.xls')
#its incomplete... need help to complete this thing

Answer 1

我认为如果使用 set() 数据类型会更好。只需为每个工作簿中的观察结果创建一个集合，然后比较这些集合，例如：

#create empty set
setA = set()
#then you loop all registers and add them to your set
setA.add(WB1_Sheet.cell_value(y,0))

#later create a setB for WB2

#to get a list of the matching records in both sets:
matchList = setA & setB

#If you want to know the items of A that are not in B:
missing = setA - setB

#If you want to know all the discrepancies
discrepancies = setA ^ setB

需要比较来自两个不同工作簿的测试用例，如果它们匹配，则将同一行其他列中的结果比较到新工作簿中

Need to compare test cases from two different workbooks and if they match then compare the results in the other columns of same row into new workbook

python

excel

compare

xlrd

xlwt
