[英]How print two times same random number?
I try to make a code that prints two equal random values in a text.我尝试制作一个在文本中打印两个相等随机值的代码。
import random
archivo=open('Ejercicio3.txt', 'w')
up=0
insert=int(input('Valor: '))
for i in range(insert):
up+=1
n1=random.randint(10, 100)
n2=random.randint(10, 100)
archivo.write(f'{up}.- {n1} - {n2} = {n1-n2}\n\n')
print(f'{up}.- {n1} - {n2} = {n1-n2}')
archivo.write(f'{n1-n2}\n')#This is the problem, because the code write numbers different random
archivo.close()
What I want is for it to do something similar to this:我想要的是它做类似的事情:
import random
archivo=open('Ejercicio1.1.txt', 'w')
up=0
insert=int(input('Valor: '))
for i in range(insert):
up+=1
n1=random.randint(10, 100)
n2=random.randint(10, 100)
archivo.write(f'{n1} - {n2} =''\n\n')
up=0
archivo.write('---------------------------------------------\n')
for i in range(insert):
up+=1
n1=random.randint(10, 100)
n2=random.randint(10, 100)
archivo.write(f'{n1-n2}''\n\n')#Except this part, I want it to be exactly the same as the result of the subtraction above.
archivo.close()
The result i want, is this: Example我想要的结果是这样的:示例
Someone can I help me?有人可以帮我吗? Thanks very much.
非常感谢。 Regards
问候
you can use random.seed()
and set the same seed two times.您可以使用
random.seed()
并设置相同的种子两次。
import random
random.seed(0)
print(random.random())
#prints a random number
random.seed(0)
print(random.random())
#prints the same random number
Just store the results in a list and then iterate over it again.只需将结果存储在列表中,然后再次对其进行迭代。
import random
archivo=open('Ejercicio1.1.txt', 'w')
up=0
results = []
insert=int(input('Valor: '))
for i in range(insert):
up+=1
n1=random.randint(10, 100)
n2=random.randint(10, 100)
results.append(n1-n2)
archivo.write(f'{n1} - {n2} = {n1 - n2} ''\n\n')
up=0
archivo.write('---------------------------------------------\n')
for i in range(insert):
up+=1
archivo.write(f'{results[i]}''\n\n')
archivo.close()
