AttributeError: 'str' 对象没有属性 'toInteger' [英] AttributeError: 'str' object has no attribute 'toInteger'

问题描述

我正在使用 python 编写代码以在 ArcMAP 中生成点 shapefile.我有 1000 个随机可能性(在 FileA 中)，我需要尝试所有这些.FileA是FileB所在位置的索引.

I'm writing a code using python to generate a point shapefile within ArcMAP. I have a 1000 random possibilities (in FileA), and I need to try all of them. The FileA is the index of the position of FileB.

此外，对于生成的每个序列，我正在查看 Voronoi 多边形的面积从 3 个点到 50 个点的每个序列(总共包含 50 个点)的演变.

In addition, for each sequence generated I'm looking at the evolution of the area of the Voronoi polygon from 3 points to 50 points in each sequence that contains a total of 50 points.

当我运行代码时，我收到一条令我困惑的消息:

When I run the code, I have this message which confuse me:

tempXYFile.writerow('{0},{1}'.format(coordinates[entry.toInteger()][0],coordinates[entry.toInteger()][1]))
AttributeError: 'str' object has no attribute 'toInteger'

我将不胜感激！

这是我的代码:

import csv

# create 1000 XY sequences
print 'Start of the script'
sequences = csv.reader(open('FileA.csv','rb'),delimiter=',')
coordinates = []

# read coordinates of volcanos and store in memory
print 'Start reading in the coordinates into the memory'
coordinates_file = csv.reader(open('FileB.csv','rb'),delimiter=',')   
for coordinate in coordinates[1:]:
    coordinates.append(coordinate)
del coordinates_file

##i = 1
for sequence in sequences:
##    print 'sequence # {0}'.format(i) 
    j = 1           
    tempXYFile = csv.writer(open('tempXY.csv','wb'),delimiter=',') #add the parameter to create a file if does not exist                  
    for entry in sequence:         
        tempXYFile.writerow('{0},{1}'.format(coordinates[entry.toInteger()][0],coordinates[entry.toInteger()][1]))
        print 'Entry # {0}: {1},{2}'.format(j, coordinates[entry.toInteger()][0],coordinates[entry.toInteger()][1]) 
        j = j + 1
    i = i + 1
    del tempXYFile

print 'End of Script'

推荐答案

Python 没有 toInteger() 函数来处理你想要使用的字符串 int(entry[]) 代替.

Python doesn't have a toInteger() function for strings you will want to user int(entry[]) instead.
