我有一个脚本可以读取XLS文件（用户输入），抓取数据并将该数据输出到.csv文件。
当我在一个XLS文件上运行脚本时，输出是正确的;但是，当我在另一个XLS文件上运行脚本时，脚本不会停在应该的位置，并将不必要的数据添加到输出文件中。
import csv, sys
from xlrd import open_workbook, XL_CELL_TEXT
input = raw_input('Input file: ')
#Place holder ID and Tank NO
#Final values will be taken from user input
termID="termid"
tankNO="tankno"
##Open *.xls file and assign sheet##
book = open_workbook(input)
sheet = book.sheet_by_index(0)
#Get Unit of Measure [(B)arrels/(G)allons] and starting row/cell
#Ranges 15 and 5 are arbitrary - used as a smallest possible range
#that will contain the first 'FT.' string

break

rawData.append(str(int(tmp)).zfill(9))
elif unit == 'B':

tmp = ('%.2f' %sheet.cell_value(row, col))

rawData.append(tmp)

break
#Break rawData into groups of 12
#And add to new list data[]

for i in xrange(0, len(rawData), 12):
data.append(rawData[i:i+12])
#Open csv file to write to
#test.csv will change to user input file name
outFile = open('test.csv', 'wb')
writeFile = csv.writer(outFile, delimiter=',', quotechar='"', quoting=csv.QUOTE_ALL)
#Add filler fields

#this only applies to the final list if it is less than 11"
if len(data[i]) < 16:
data[i].extend([''] * (16 - len(data[i])))
#The following three lines are filler and do not change
data[i].append(unit) #Add UOM
data[i].append('N') #Outage = N
data[i].append("") #Key Fill
writeFile.writerow(data[i])
outFile.close()
如果我使用找到here的输入文件，脚本将停止循环，并且输出文件完美无缺：

如果将此第二个输出与输入文件进行比较，则不应包含输出文件的最后一行，并且当包含它时，第5列是错误的。
答案 0 :(得分：0)
进行一些测试并想出一个解决方案 - 可能不是最好的，但它现在正在运行：
我在脚本开始抓取数据（check）之前添加了一个变量line 32，该数据最初设置为0.脚本检查当前单元格是否为float后，检查单元格的值是否大于check。如果它大于check，请将值添加到rawData[]并将check设置为单元格的值。这样，check将始终等于rawData[-1]，因此当需要数据结束时，会忽略任何低于添加到列表中的最后一个数字的内容。
#Grab Raw values from XLS and process based on UOM
rawData = []
check = 0
for col in range(startCol, sheet.ncols, 2):
for row in range(startRow, sheet.nrows):
if isinstance(sheet.cell_value(row, col), float):
if sheet.cell_value(row, col) > check:
if unit == 'G':
print type(sheet.cell_value(row, col)), " - ", sheet.cell_value(row, col)
tmp = round(sheet.cell_value(row, col))
rawData.append(str(int(tmp)).zfill(9))
check = int(sheet.cell_value(row, col))
elif unit == 'B':
print type(sheet.cell_value(row, col)), " - ", sheet.cell_value(row, col)
tmp = ('%.2f' %sheet.cell_value(row, col))
tmp = str(tmp).replace(".", "").zfill(9)
rawData.append(tmp)
check = int(sheet.cell_value(row, col))
else:
break
