如何在使用Python的numpy随机选择时指定随机种子? [英] How to specify a random seed while using Python's numpy random choice?

问题描述

我有四个字符串的列表.然后在Pandas数据框中，我想创建一个变量，从该列表中随机选择一个值，并将其分配给每一行.我正在使用numpy的随机选择，但是阅读其文档时，没有任何种子选项.如何为随机分配指定随机种子，以便每次随机分配都相同?

I have a list of four strings. Then in a Pandas dataframe I want to create a variable randomly selecting a value from this list and assign into each row. I am using numpy's random choice, but reading their documentation, there is no seed option. How can I specify the random seed to the random assignment so every time the random assignment will be the same?

service_code_options = ['899.59O', '12.42R', '13.59P', '204.68L']
df['SERVICE_CODE'] = [np.random.choice(service_code_options ) for i in df.index]
