从此代码创建坐标对 [英] Create a coordinate pair from this code
本文介绍了从此代码创建坐标对的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
这是我当前的代码
a_reader = None
a_reader = open('data.csv', 'rU')
a_csv_reader = csv.reader(a_reader)
for row in a_csv_reader:
print row
a_reader.close()
count = 0
sum = 0.0
a_reader = open('data.csv', 'rU')
a_csv_reader = csv.reader(a_reader)
a_csv_reader.next()
for row in a_csv_reader:
if count != 0 and row[0] != '':
sum = sum + float(row[0])
count = count + 1
a_reader.close()
print 'Number of lines is:',count
print 'Sum is:',sum
return listStation
这将产生以下结果
['1', '476050', '7709929']
['2', '473971', '7707713']
['3', '465676', '7691097']
['4', '515612', '7702192']
['5', '516655', '7704405']
['6', '519788', '7713255']
['7', '538466', '7683341']
Number of lines is: 8
Sum is: 28.0
好的,所以我想要的输出显示在下面的双重列表中.
Ok so the output that I want is shown below in a double list.
[[476050, 7709929],[473971, 7707713],[465676, 7691097],[515612, 7702192],[516655, 7704405],[519788, 7713255],[538466, 7683341]]
如何更改代码以将结果生成为双重列表,如上所示.是否可以创建一个坐标对的双重列表,如上所示.你能帮我吗?
How can I alter my code to produce the result as a double list as shown above. Is it possible to create a doublelist of coordinate pairs as shown above. Can you help me?
感谢您的帮助.
推荐答案
切掉最后两个元素,然后追加.
Slice off the last two elements, then append.
>>> ['1', '476050', '7709929'][1:3]
['476050', '7709929']
