pycharm怎么注释？

pycharm中同时注释多行代码快捷键：

1、选中要注释的代码，然后Ctrl + '/'

具体效果：

import matplotlib.pyplot as plt
 
data_dir = 'D:/Python/neural network/CIFAR10-Guoqingxu/data/'
BATCH_SIZE = 2
image_batch, label_batch = read_cifar10(data_dir,
                                        is_train=True,
                                        batch_size=BATCH_SIZE,
                                        shuffle=True)
# import matplotlib.pyplot as plt
# 
# data_dir = 'D:/Python/neural network/CIFAR10-Guoqingxu/data/'
# BATCH_SIZE = 2
# image_batch, label_batch = read_cifar10(data_dir,
#                                         is_train=True,
#                                         batch_size=BATCH_SIZE,
#                                         shuffle=True)

2、折叠要注释的代码，然后Ctrl + '/'

效果如下：
