Python offersrandommodule that can generate random numbers. These are pseudo-random number as the sequence of number generated depends on the seed. If the seeding value is same, the sequence will be the same. For example, if you use 2 as the seeding value, you will always see the followin...
Tuples have many uses in Python programming. 一个特别重要的用例是当您希望从Python函数返回多个对象时。 One especially important use case is when you want to return more than one object from your Python function. 在这种情况下,您通常会将所有这些对象包装在一个元组对象中,然后返回该元组。 In that...

Python’s os.urandom() function is used by both secrets and uuid (both of which you’ll see here in a moment). Without getting into too much detail, os.urandom() generates operating-system-dependent random bytes that can safely be called cryptographically secure:...
