random.randrange is a function in the Python programming language that allows you to generate a random number within a specified range. It is part of the random module in Python which provides tools for generating random numbers.
To use random.randrange
you first need to import the random module at the beginning of your Python ｓｃｒｉｐｔ. This can be done by adding the following line of code:
```python
import random
```
Once you have imported the random module
you can use the random.randrange function to generate a random number within a specified range. The syntax for the random.randrange function is as follows:
```python
random.randrange(start
stop
step)
```
Where:
- start: the starting point of the range (inclusive)
- stop: the ending point of the range (exclusive)
- step: the step size for generating numbers within the range (optional
default is 1)
For example
if you want to generate a random number between 1 and 10
you can use the following code:
```python
random_number = random.randrange(1
11)
print(random_number)
```
This will generate a random number between 1 and 10 and print it to the console.
You can also specify a step size for generating numbers within the range. For example
if you want to generate a random number between 1 and 10 with a step size of 2
you can use the following code:
```python
random_number = random.randrange(1
11
2)
print(random_number)
```
This will generate a random number between 1 and 10 with a step size of 2 and print it to the console.
In conclusion
random.randrange is a useful function in Python for generating random numbers within a specified range. By using this function
you can easily add randomness and variability to your programs.
