python - 为什么该程序在Linux Python Shell上运行却在Windows上不能运行？

我在Linux上用Python2.6.2运行这个程序，它运行良好，返回十进制值，但当我在Windows上用Python2.7.2运行它时，它不起作用，只是给了一段时间一个空白空间，然后是一个内存错误，但我不明白为什么..我需要它在Windows上运行一个计算股票权益（ROE）的程序。谢谢。
运行程序所需的CSV文件是here。
.

import csv

csvname = raw_input("Enter csv name: ")

sbuxfile = csv.reader(open(csvname), delimiter=',', quotechar='|')

# List of Data
row5, row8, row3, row7, avgequity, roe1, roe2 = ([] for i in range(7))

count = 0
# Grab data and numerical values from CSV.
for row in sbuxfile:
  count += 1
  if count == 8:
     row8 = row
  elif count == 5:
     row5 = row
  elif count == 3:
     row3 = row
  elif count == 7:
     row7 = row


a = 1

# Perform calculations for average equity and ROE.
while a < 8 :
   if a == 1:
     avgequity.append(round(float(row8[a]),2))
     roe1.append(float(row5[a]) / float(row8[a]))
     roe2.append((float(row5[a]) / float(row3[a])) * (float(row3[a]) / float(row7[a])) * (float(row7[a]) / float(row8[a])))
   else:
     avgequity.append(round(float((row8[a]),2) + float(row8[a-1]))/2)
     roe1.append(float(row5[a]) / float(row8[a]))
     roe2.append((float(row5[a]) / float(row3[a])) * (float(row3[a]) / float(row7[a])) * (float(row7[a]) / ((float(row8[a]) + float(row8[a-1]))/2)))
     a+=1

print "\nAverage equity is " + str(avgequity) + "\n"
print "ROE method 1 is " + str(roe1) + "\n"
print "ROE method 2 is " + str(roe2)

最佳答案

我对你的剧本做了一些修改。
它在Python 2.7for Windows上运行良好。
代码如下：

import csv

csvname = raw_input("Enter csv name: ")

sbuxfile = csv.reader(open(csvname), delimiter=',', quotechar='|')
# List of Data
row5, row8, row3, row7, avgequity, roe1, roe2 = ([] for i in range(7))

count = 0
# Grab data and numerical values from CSV.
for row in sbuxfile:
  count += 1
  if count == 8:
     row8 = row
  elif count == 5:
     row5 = row
  elif count == 3:
     row3 = row
  elif count == 7:
     row7 = row


a = 1

# Perform calculations for average equity and ROE.
while a < 8 :
   if a == 1:
     avgequity.append(round(float(row8[a]),2))
     roe1.append(float(row5[a]) / float(row8[a]))
     roe2.append((float(row5[a]) / float(row3[a])) * (float(row3[a]) / float(row7[a])) * (float(row7[a]) / float(row8[a])))
     a+=1   #added this line
   else:
     avgequity.append(round(float(row8[a]),2) + float(row8[a-1])/2) #rewrote this line as it had an error
     roe1.append(float(row5[a]) / float(row8[a]))
     roe2.append((float(row5[a]) / float(row3[a])) * (float(row3[a]) / float(row7[a])) * (float(row7[a]) / ((float(row8[a]) + float(row8[a-1]))/2)))
     a+=1

print "\nAverage equity is " + str(avgequity) + "\n"
print "ROE method 1 is " + str(roe1) + "\n"
print "ROE method 2 is " + str(roe2)

结果是：
平均权益为[2071.11、3505.7650000000003、3325.3650000000002、3273.64000000003、3398.375、4187.76、5197.5499999999]
净资产收益率方法1为[0.12812453225565035，0.157427910987332495，0.23651124740462906，0.2532005689900426，0.29448540356894，0.1283120464917753，0.2573271287452037]
ROE方法2为[0.12812453225565038，0.17126298080734237，0.21680660107401206，0.261305881076202，0.29811440335236883，0.14664666034500227，0.2814118207249569]
