我想使用列名將 csv 檔案拆分為 2 個串列
CSV 檔案:
Molecule Name,SMILES
ZINC53 (Aspirin),CC(=O)Oc1ccccc1C(=O)O
ZINC7460 (Vatalanib),Clc1ccc(Nc2nnc(Cc3ccncc3)c3ccccc23)cc1
ZINC1493878 (Sorafenib),CNC(=O)c1cc(Oc2ccc(NC(=O)Nc3ccc(Cl)c(C(F)(F)F)c3)cc2)ccn1
代碼:
namelist = list()
smileslist = list()
with open('./file.csv', 'r') as f:
f = csv.reader(f, delimiter=',')
columns = next(f)
type_col1 = columns.index("Molecule Name")
type_col2 = columns.index("SMILES")
for column in f:
if type_col1 == 'Molecule Name':
namelist.append(column)
elif type_col2 == 'SMILES':
smileslist.append(column)
uj5u.com熱心網友回復:
使用pandas 庫,您可以輕松地做到這一點:
import pandas as pd
df = pd.read_csv("./file.csv")
namelist = df["Molecule Name"].tolist()
smileslist = df["SMILES"].tolist()
print(namelist)
print(smileslist)
或者,如果您更喜歡使用 csv 閱讀器,您可以按以下方式進行操作:
import csv
namelist = list()
smileslist = list()
with open("./file.csv", "r") as f:
f = csv.reader(f, delimiter=',')
columns = next(f)
index_col1 = columns.index("Molecule Name")
index_col2 = columns.index("SMILES")
for column in f:
namelist.append(column[index_col1])
smileslist.append(column[index_col2])
