Read Shape Files in Python

import shapefile 
#read shape file
sf = shapefile.Reader("F:\itrace\shape\gshhg-shp-2.3.7\GSHHS_shp\l\GSHHS_l_L1.shp")
border = sf.shapes()
## .shapes() will read the geomeray data.
border_points = []
shp_x = []
shp_y = []
for i in range(len(border)):
     border_points.append(border[i].points)
     x,y = zip(*border_points[i])
     x0 = np.array(x)
     idx = np.where(x0<0)[0]
     if len(idx)>0:
         x0[idx] = x0[idx] + 360

X = [1, 2, 3, 4, 5, 6]
y = [0, 1, 0, 0, 1, 1]
zipped_data = list(zip(X, y))  
# 将样本和标签一 一对应组合起来,并转换成list类型方便后续打乱操作

random.shuffle(zipped_data)  
# 使用random模块中的shuffle函数打乱列表，原地操作，没有返回值

#list(zip(*zipped_data))   #反向解压
new_zipped_data = list(map(list, zip(*zipped_data)))  
# zip(*)反向解压，map()逐项转换类型，list()做最后转换

new_X, new_y = new_zipped_data[0], new_zipped_data[1]  
# 返回打乱后的新数据

print('X:',X,'\n','y:',y)
print('new_X:',new_X, '\n', 'new_y:',new_y)
