Python的列表等變數的宣告必須要在函式定義與函式呼叫之前

原始碼
—–這個程式碼作用是呼叫Linux應用終端操作來實現計算,並把計算結果取出來,組成相似矩陣,有五組值也就是有五組相似矩陣,這個是我做蛋白質結構預測用到的,自己寫的,分享出來給大家,如有疑惑,歡迎評論區交流。
# 此程式碼主要為說明問題,後面我會貼上完整程式碼以及資料。
def cal_simi(n):
file = os.popen('cd '+path[n-1]+';ls').readlines()
RMSD_simi = []
TMscore_simi = []
MasSubscore_simi = []
GDTTSscore_simi = []
GDTHAscore_simi = []
for fileName1 in file:
temp1 = [];temp2=[];temp3=[];temp4=[];temp5=[]
for fileName2 in file:
comm = 'cd /home/stern/Desktop/TMscore;' + 'sudo ./TMscore ' + path[n-1] + fileName1[:-1] +' '+ path[n-1] + fileName2[:-1]
# storge the result of the command in data
data = os.popen(comm).readlines()
temp1.append(data[14][32:38]);temp2.append(data[16][14:20]);temp3.append(data[17][14:20])
temp4.append(data[18][14:20]);temp5.append(data[19][14:20])
RMSD_simi.append(temp1)

MasSubscore_simi.append(temp3)
GDTTSscore_simi.append(temp4)
GDTHAscore_simi.append(temp5)
p1 = np.median(RMSD_simi);p2 = np.median(TMscore_simi);p3 = np.median(MasSubscore_simi)
p4 = np.median(GDTTSscore_simi);p5 = np.median(GDTHAscore_simi)
for i in range(len(file)):
RMSD_simi[i][i] = p1
TMscore_simi[i][i] = p2
MasSubscore_simi[i][i] = p3
GDTTSscore_simi[i][i] = p4
GDTHAscore_simi[i][i] = p5
return RMSD_simi,TMscore_simi,MasSubscore_simi,GDTTSscore_simi,GDTHAscore_simi
Xn = ['1abv_','1af7_','1cqkA','1csp_','1dcjA','256bA']
path = ['/home/stern/Desktop/1abv_/','/home/stern/Desktop/1af7_/','/home/stern/Desktop/1cqkA/',

# fsadf
RMSD_simi1 = []
TMscore_simi1 = []
MasSubscore_simi1 = []
GDTTSscore_simi1 = []
GDTHAscore_simi1 = []
RMSD_simi1,TMscore_simi1,MasSubscore_simi1,GDTTSscore_simi1,GDTHAscore_simi1=cal_simi(1)
print RMSD_simi1[1][1]
print TMscore_simi1[2][2]
print MasSubscore_simi1[3][3]
print GDTTSscore_simi1[4][4]
print GDTHAscore_simi1[5][5]
執行結果
—–執行結果,錯誤如下,如果把# fsadf後面的列表的宣告提到函式定義的前面,則錯誤就沒有了,列表的宣告必須要在函式的呼叫之前,這個就更不用講了,如果你不在函式呼叫之前的話,會提示列表不存在。。
