Modulo 10^9 7 python-CodePudding

I have a list let's say : [1,3,5,6....,n] to very large number, that I need to report each number in the list in a new list but in "modulo 10^9 7" format in python.

How do I do it please?

I tried to search for it and people answer it's (n%m=p) and the solution is p, but I guess that's not it.

To perform the modulo operation with a divisor of 10^9 7 in Python, you can use the % operator. For example:

Copy code x = 4 y = (x % (109 7)) print(y) # Output: 4 This will give you the remainder when x is divided by 109 7. In this case, the output will be 4.

You can also use the % operator to perform modulo operations with other divisors. For example:

Copy code x = 4 y = (x % 3) print(y) # Output: 1 This will give you the remainder when x is divided by 3. In this case, the output will be 1.

Some ways to do it. The first method is called list comprehension, and you can find many examples of it on stack overflow and elsewhere.

list1 = [1, 3, 5, 6, 201, 99121, 191929912, 8129391828989123]
modulus = 10**9   7
list2 = [x % modulus for x in list1]  # example of list comprehension

or using map

list2 = list(map(lambda x: x % modulus, list1))

or perhaps the least elegant

list2 = []
for x in list1:
    list2.append(x % modulus)
