import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns
import pickle as pkl
from __future__ import division
sns.set(style="darkgrid")
sns.distplot(featureSet[featureSet['label']=='0']['len of url'],color='green',label='Benign URLs')
sns.distplot(featureSet[featureSet['label']=='1']['len of url'],color='red',label='Phishing URLs')
sns.plt.title('Url Length Distribution')

Don't use sns.plt. Instead import matplotlib.pyplot as pltand use it directly.
不要使用sns.plt. 而是import matplotlib.pyplot as plt直接使用它。
Appart the code should run fine. I created the following minimal runnable example
Appart 代码应该可以正常运行。我创建了以下最小的可运行示例
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd
import seaborn as sns
df = pd.DataFrame({"label" : np.random.randint(2, size=100).astype(str),
"data" : np.random.rayleigh(size=100)})
sns.set(style="darkgrid")
sns.distplot(df[df['label']=='0']['data'],color='green',label='Benign URLs')
sns.distplot(df[df['label']=='1']['data'],color='red',label='Phishing URLs')
plt.title('Url Length Distribution')
plt.legend(loc='upper right')
plt.xlabel('Length of URL')
plt.show()
which produces the following output
产生以下输出
If it does not work for you, consider upgrading your matplotlib and seaborn version. The above is produced with matplotlib 2.2.2 and seaborn 8.1.
如果它不适合您，请考虑升级您的 matplotlib 和 seaborn 版本。以上是使用 matplotlib 2.2.2 和 seaborn 8.1 生成的。

Just delet color atribute.
只需删除颜色属性。
Delete color='green'and color = 'red'and everything will work ok.
删除color='green'和color = 'red'一切都会正常工作。
