通過從 array1 中的所有第一列與 array2 中的所有行查找匹配元素來檢索行元素

Question

我在 python 中處於初級水平。 我在從數組中檢索元素時遇到問題。

face_splt=[]
with open ('Face_temp.txt','rt') as ifile, open('Face.txt', 'w') as ofile:
    rows = np.array((ifile.readlines()[1::4]))
    for elm in rows:
        face_splt = elm.split()
        Face_array.append(face_splt[2:])
        ofile.write(str(face_splt[2:]))
    ofile.close()

Vertex_array=[]
vertex_splt=[]    
with open ('Vertex_temp.txt','rt') as ifile, open('Vertex.txt', 'w') as ofile:
    rows = np.array((ifile.readlines()[1:]))
    for elm in rows:
        vertex_splt = elm.split()
        Vertex_array.append(vertex_splt[:4])
        ofile.write(str(vertex_splt[:4]))
    ofile.close()

Vertex_in=[]
Vertex_InList=[]
for i in Vertex_array:
    if (((0<float(i[1]))and(float(i[1])<1))and((0<float(i[2]))and(float(i[2])<1))and((0<float(i[3]))and(float(i[3])<1))):
        vertex_id=i[0]
        vertex_x=i[1]
        vertex_y=i[2]
        vertex_z=i[3]
        Vertex_in=[vertex_id,vertex_x,vertex_y,vertex_z]
        Vertex_InList.append(Vertex_in)

使用上面的代碼，我設法從文件中獲取所需的數據來執行操作。 現在，我有 2 個 arrays、Vertex_InList 和 Face_array，我必須從中獲取 Vertex_InList 的坐標（第 2 到第 4 列）。 這是通過從 Vertex_InList 的第 1 列中找到與 Face_array 行中的所有元素匹配的元素。

Vertex_InList =

請幫助我找到解決方案。 先感謝您。

Answer 1

我仍然不完全理解這個問題，這是基於我的理解

vertex_InList = [['7', '0.434151598161', '0.327663532237', '0.795784363147'],
['10', '0.178728872392', '0.472579545895', '0.429825098041'],
['11', '0.186998765476', '0.462472809438', '0.361331160813'],
['30', '0.503947601476', '0.807076535216', '0.272964215305'],
['32', '0.181969901270', '0.481439284558', '0.447414063030'],
['35', '0.557938786910', '0.677531596182', '0.778820222491'],
['44', '0.394789918890', '0.407632437561', '0.809129530152']]

face_array =[
    ['10', '11', '12'],
    ['30', '32', '35']]


# implementation

solution = []
for row in range(len(face_array)):
    inner = []
    for col in range(len(face_array[row])):
        for vRow in vertex_InList:
            if face_array[row][col] == vRow[0]:
                inner.append(vRow[1:4])
    solution.append(inner)
print(solution)

#output

[[['0.178728872392', '0.472579545895', '0.429825098041'], ['0.186998765476', '0.462472809438', '0.361331160813'], ['0.394789918890', '0.407632437561', '0.809129530152']],
