‘贰’ Python 生成随机点坐标

importrandom
importnumpyasnp
List=np.array([(0,0),(1,1),(1.6,1.8),(3,3)])

d=0.5

defget_random(low,high):
return((high-low)*random.random()+low)

n=0
whilen<100000:
x=get_random(0,3)
y=get_random(0,3)
rand_tuple=np.array([x,y])
tmp_dist=np.sqrt(np.sum(np.square(List-rand_tuple),axis=1))
tmp_dist_bool=tmp_dist>=d
ifnp.sum(tmp_dist_bool)==len(List):
print(x,y)
break
n+=1
ifn==100000:
print("After",n,"tries,can'tgetarandompoint!!")

‘叁’ python画图如何得到坐标

画图的默认原点都是左上角，可以设立坐标中心点进行偏移。

‘肆’ python怎么修改Point坐标

def coordinate(x, y):
if x>0:
if y>0:
a = 1
else:
a = 2
else:
if y>0:
a = 3
else:
a = 4
return a #根据x,y返回aif __name__ == "__main":
print 'Please insert X,Y'
x = input('Please insert X')
y = input('Please insert Y')
print coordinate(x,y)

‘伍’ 用python怎么获得网页上任何一个对象的x，y坐标呢

你的要求不容易实现！固定格式的网页内容还好，可以看网页源码进行分析编程。非固定的网页不容易实现。你不会是想编个浏览器吧！

不知道你是基于什么原因提出这样的需求的？可以将你的原因说一说，让大家帮你想想办法。

‘陆’ python从两个列表中取值，生成坐标

for i in X:

for j in Y:

d=[i,j]

print(d)

后面没有截图，太长了，一共144行。

希望可以帮到你

‘捌’ python如何定义坐标

def coordinate(x, y):
if x>0:
if y>0:
a = 1
else:
a = 2
else:
if y>0:
a = 3
else:
a = 4
return a #根据x,y返回aif __name__ == "__main":
print 'Please insert X,Y'
x = input('Please insert X')
y = input('Please insert Y')
print coordinate(x,y)

‘玖’ 在python怎么读取txt文件中的坐标。

importre

withopen('te.txt')asA:
foreachlineinA:
tmp=re.split("s+",eachline.rstrip())
x.append(tmp[0])
y.append(tmp[1])
printx,y

‘拾’ 如何用Python批量获取经纬度坐标

python根据地址获取经纬度方法一：
from geopy.geocoders import Nominatim
#使用geopy查询
def geocodeN(address):
gps=Nominatim()
location=gps.geocode(address)
return location.longitude,location.latitude

使用Geopy包 ： github.com/geopy/geopy （仅能精确到城镇，具体街道无结果返回）
另外还有一种使用高德地图或网络地图API的方法，有兴趣的朋友可以参考下。
