The random. uniform() function returns a random floating-point number between a given range in Python. For example, It can generate a random float number between 10 to 100 Or from 50.50 to 75.5.A range of floats is a list of numbers from start to stop incremented with a specified step interval. Ranges are typically “open”, meaning the value stop is omitted from the series. For example, a range from 1.0 to 3.0 with a step of 0.5 is [1.0, 1.5, 2.0, 2.5] .The Python range() works only with integers. It doesn’t support the float type, i.e., we cannot use floating-point/decimal value in any of its arguments. For example, If you use range() with float step argument, you will get a TypeError ‘float’ object cannot be interpreted as an integer .
- import random n = random. random() print(n)
- import random n = random. randint(0,22) print(n)
- import random randomlist = [] for i in range(0,5): n = random. randint(1,30) randomlist. …
- import random #Generate 5 random numbers between 10 and 30 randomlist = random.

How do you find the max float value in Python?
Max float Value With the sys.
In Python, we can use the sys. maxint function inside the built-in sys module to find out the maximum value that can be stored in an integer variable. We can also use the same sys module to find out the maximum value that can be stored inside a float variable with the sys. float_info .
