Hello guys, here we are going to learn about **How to convert positive numbers to negative in Python?** the conversion of positive numbers into negative as well as negative numbers into positive.

Example :

```
Input : [1,2,3]
Output : [-1,-2,-3]
Input : [-1,2,-3,4,5]
Output : [1,-2,3,-4,-5]
```

so here are the some methods which is used mostly to convert positive numbers to negative numbers.

## How to convert positive numbers to negative in Python?

**How to convert positive numbers to negative in Python?**to convert positive numbers to negative in Python It is the simplest method and mostly used in programmings:

**for num in range(1,6): print(-abs(num))**In this method, you have to use just -abs() and it will convert the numbers into negative phase. as you can see it in my output.**convert positive numbers to negative in Python**to convert positive numbers to negative in Python This is a list comprehension method. In this method use the numbers in a list like this way, In this method, use numbers in a list and in output it will give you the opposite phase numbers.

**Method : 1**

It is the simplest method and mostly used in programmings.

```
for num in range(1,6):
print(-abs(num))
```

Output :

```
-1
-2
-3
-4
-5
```

In this method, you have to use just -abs() and it will convert the numbers into negative phase. as you can see it in my output.

**Method : 2**

This is a list comprehension method. In this method use the numbers in a list like this way,

```
def Convert(numbers):
return [ -i for i in numbers ]
numbers = [1, -2, 3, -4]
print(Convert(numbers))
```

Output :

`[-1, 2, -3, 4]`

In this method, use numbers in a list and in output it will give you the opposite phase numbers.

**Method : 3**

You can also use this method,

```
for num in range(1,5):
num ='-' + str(num).strip()
print(num)
```

Output :

```
-1
-2
-3
-4
```

Thus, these are the methods you can use to change the numbers. from all of these methods, first one is most easy and widely use where **abs()** used for change into negative while **-abs() **used for to get positive numbers as well as.
