假设您有以下目录,其中包含多个shapefile:
MyFolder
|
|---S1.shp
|---S2.shp
|---S3.shp
|---
|---
|---S50.shp
并且您希望为其中每一个创建一个图表,并将其称为相同(例如,与S1.shp
相关联的图表称为S1
)。
我试图在for循环中执行此操作:
import networkx as nx
import os
myfolder=r'C:\Users\MyName\MyFolder'
os.chdir(myfolder)
for root, dirs, filenames in os.walk(myfolder):
for f in filenames:
if f.endswith('.shp') and f[0]=='S': #Consider only the files with an "S" in their name
G=nx.read_shp(f)
pos={k: v for k,v in enumerate(G.nodes())}
pos_x = {k:(round(a,4),round(b,4)) for k,(a,b) in pos.items()}
graph_name=f.split('.', 1)[0]
GG=nx.Graph(name=graph_name)
GG.add_nodes_from(pos_x.keys())
现在GG=nx.Graph(name=graph_name)
行没有按照我的意愿行事,因为图表仍称为GG
,而不是S1
等。正确的图形名称存储在GG.name
中,但我无法通过调用其GG.name来检索图形。
有没有办法可以为图表指定 文件名的名称,而不包含扩展名?
答案 0 :(得分:1)
您可以将GG
设为将文件名映射到图表的字典:
import networkx as nx
import os
myfolder = r'C:\Users\MyName\MyFolder'
os.chdir(myfolder)
GG = dict()
for root, dirs, filenames in os.walk(myfolder):
for f in filenames:
if f.endswith('.shp') and f.startswith('S'):
G = nx.read_shp(f)
pos_x = {k: (round(a, 4), round(b, 4))
for k, (a, b) in enumerate(G.nodes())}
graph_name, graph_ext = os.path.splitext(f)
GG[graph_name] = nx.Graph(name=graph_name)
GG[graph_name].add_nodes_from(pos_x.keys())
然后S1.shp
可以访问与GG['S1']
相关联的图表。
