使用Rdkit对SDF文件进行分割

import rdkit
from rdkit import Chem
suppl = Chem.SDMolSupplier('enamine_3d.sdf')
count = len(suppl)
2102303
# out_sdf输出为sdf文件
def out_sdf(lig_list,filename):
    writer = Chem.SDWriter(filename)
    for i in lig_list:
        writer.write(i)
    writer.close()
    return
# 将SDF分割为10000为单位的小块
cut = 10000
for i in range(len(suppl)):
    tmp = []
    while len(tmp) < cut:
        try:
            tmp.append(next(suppl))
        except StopIteration:
            break
  out_sdf(tmp,str(i)+'.sdf'）
