python - 错误语法错误：解析时出现意外 EOF

Question

运行这部分代码时出现错误。尝试更改目录并移动文件夹以使其正常工作，但它不会让步。

输入：

import os
from collections import defaultdict
import pandas as pd
import numpy as np
import matplotlib.pyplot as plt
get_ipython().magic('matplotlib inline')

import warnings
warnings.filterwarnings('ignore')

dataset_root = 'Python/Data/nsl-kdd'

train_file = os.path.join(dataset_root, 'KDDTrain+.txt')
test_file = os.path.join(dataset_root, 'KDDTest+.txt')

header_names = ['duration', 'protocol_type', 'service', 'flag', 'src_bytes', 'dst_bytes', 'land', 'wrong_fragment', 'urgent', 'hot', 'num_failed_logins', 'logged_in', 'num_compromised', 'root_shell', 'su_attempted', 'num_root', 'num_file_creations', 'num_shells', 'num_access_files', 'num_outbound_cmds', 'is_host_login', 'is_guest_login', 'count', 'srv_count', 'serror_rate', 'srv_serror_rate', 'rerror_rate', 'srv_rerror_rate', 'same_srv_rate', 'diff_srv_rate', 'srv_diff_host_rate', 'dst_host_count', 'dst_host_srv_count', 'dst_host_same_srv_rate', 'dst_host_diff_srv_rate', 'dst_host_same_src_port_rate', 'dst_host_srv_diff_host_rate', 'dst_host_serror_rate', 'dst_host_srv_serror_rate', 'dst_host_rerror_rate', 'dst_host_srv_rerror_rate', 'attack_type', 'success_pred']

col_names = np.array(header_names)

nominal_idx = [1, 2, 3]
binary_idx = [6, 11, 13, 14, 20, 21]
numeric_idx = list(set(range(41)).difference(nominal_idx).difference(binary_idx))

nominal_cols = col_names[nominal_idx].tolist()
binary_cols = col_names[binary_idx].tolist()
numeric_cols = col_names[numeric_idx].tolist()

category = defaultdict(list)
category['benign'].append('normal')

with open('Python/Data/nsl-kdd/training_attack_types.txt', 'r') as f:
    for line in f.readlines():
        attack, cat = line.strip().split(' ')
        category[cat].append(attack)

输出：

  File "<ipython-input-132-87b8f2b05f6e>", line 1
    with open('Python/Data/nsl-kdd/training_attack_types.txt', 'r') as f:
                                                                         ^
SyntaxError: unexpected EOF while parsing

我需要能够克服这个错误并阅读文本文件。
