Can't I set the condition in Python tf.variable(tf.random.normal([1])?

We use pie lines to code random numbers and put them into necessary formulas to extract results.

tf.Variable(tf.random.normal([1])

Is there a way to make the random numbers that come out here come within the required range? (e.g. only positive numbers, or between 0 and 1)

And

I wonder what it does when you put numbers in each place, such as tf.variable(tf.random.normal([1],,).
