I don't want to affect only some random number seeds.

For example, when func1 is called in the second line of test.py in the following two files, seed is fixed to 42, and b is also generated from seed42.I want to cause it without fixing the seed just now.
func.py

import numpy as np
def func1():
    np.random.seed (42)
    return np.random.rand()

test.py

import func
a=func.func1()
b=np.random.rand()

python

Why don't you create a new generator using numpy.RandomState()?

b=np.random.RandomState().rand()

You can initialize with a different value by calling np.random.seed without arguments.

 from func import func1
import numpy as np


def func1():
    np.random.seed(42)#Static seed
    return np.random.rand()


def func2():
    np.random.seed()#Randomseed
    return np.random.rand()


def func3():
    np.random.seed(100)#Other static seed
    return np.random.rand()


defmain():
    val_1 = func1()
    val_2 = func2()
    val_3 = func3()
    print("val_1:{:.2}\nval_2:{:.2}\nval_3:{:.2}\n".format(val_1,val_2,val_3))


if__name__=="__main__":
    main()
