如何设置＆＃39; for循环的边界？

Question

我有一个数据集，我想在网格框中绘制数据。对我来说最好的方式似乎是for循环，但我无法让它工作。我对代码应该是什么的假设是：

for lat in range(53.22010374071,53.46673202514641) & lon in range(1.22201037407, 1.33312034607):

它出现了错误：

TypeError: range() integer end argument expected, got float.

Answer 1

build in range（）仅适用于整数循环。尝试使用例如numpy linspace ：     import numpy

lat_start = 53.22010374071
lat_stop = 53.46673202514641

lon_start = 1.22201037407
lon_stop = 1.33312034607

for lat in numpy.linspace( lat_start, lat_stop, 100 ):
  for lon in numpy.linspace( lon_start, lon_stop, 100 ):
     print "Doing grid at %f %f " % (lat,lon)

给我的输出如下：

Doing grid at 53.441820 1.283738 
Doing grid at 53.441820 1.284860 
Doing grid at 53.441820 1.285983 
Doing grid at 53.441820 1.287105
