# Python program to print negative numbers in a list

• Difficulty Level : Easy
• Last Updated : 02 Jan, 2023

Given a list of numbers, write a Python program to print all negative numbers in the given list.

Example:

```Input: list1 = [12, -7, 5, 64, -14]
Output: -7, -14

Input: list2 = [12, 14, -95, 3]
Output: -95```

Example #1: Print all negative numbers from the given list using for loop Iterate each element in the list using for loop and check if the number is less than 0. If the condition satisfies, then only print the number.

## Python3

 `# Python program to print negative Numbers in a List`   `# list of numbers` `list1 ``=` `[``11``, ``-``21``, ``0``, ``45``, ``66``, ``-``93``]`   `# iterating each number in list` `for` `num ``in` `list1:`   `    ``# checking condition` `    ``if` `num < ``0``:` `    ``print``(num, end``=``" "``)`

Output:

`-21 -93 `

Example #2: Using while loop

## Python3

 `# Python program to print negative Numbers in a List`   `# list of numbers` `list1 ``=` `[``-``10``, ``21``, ``-``4``, ``-``45``, ``-``66``, ``93``]` `num ``=` `0`   `# using while loop` `while``(num < ``len``(list1)):`   `    ``# checking condition` `    ``if` `list1[num] < ``0``:` `        ``print``(list1[num], end``=``" "``)`   `    ``# increment num` `    ``num ``+``=` `1`

Output:

`-10 -4 -45 -66 `

Example #3: Using list comprehension

## Python3

 `# Python program to print negative Numbers in a List`   `# list of numbers` `list1 ``=` `[``-``10``, ``-``21``, ``-``4``, ``45``, ``-``66``, ``93``]`   `# using list comprehension` `neg_nos ``=` `[num ``for` `num ``in` `list1 ``if` `num < ``0``]`   `print``(``"Negative numbers in the list: "``, ``*``neg_nos)`

Output

`Negative numbers in the list:  -10 -21 -4 -66`

Example #4: Using lambda expressions

## Python3

 `# Python program to print negative Numbers in a List`   `# list of numbers` `list1 ``=` `[``-``10``, ``21``, ``4``, ``-``45``, ``-``66``, ``93``, ``-``11``]`     `# we can also print negative no's using lambda exp.` `neg_nos ``=` `list``(``filter``(``lambda` `x: (x < ``0``), list1))`   `print``(``"Negative numbers in the list: "``, ``*``neg_nos)`

Output

`Negative numbers in the list:  -10 -45 -66 -11`

## Python3

 `l``=``[``12``, ``-``7``, ``5``, ``64``, ``-``14``]` `print``([a ``for` `j,a ``in` `enumerate``(l) ``if` `a<``0``])`

Output

`[-7, -14]`

## Python3

 `# Python program to print negative Numbers in a List`   `# list of numbers` `list1 ``=` `[``11``, ``-``21``, ``0``, ``45``, ``66``, ``-``93``]` `res ``=` `[]` `list2 ``=` `list``(``map``(``str``, list1))` `for` `i ``in` `range``(``0``, ``len``(list2)):` `    ``if``(list2[i].startswith(``"-"``)):` `        ``res.append(``str``(list1[i]))` `res ``=` `" "``.join(res)` `print``(res)`

Output

`-21 -93`

## Python3

 `# Python program to print negative Numbers in a List` `import` `numpy as np` `# list of numbers` `list1 ``=` `[``-``10``, ``21``, ``4``, ``-``45``, ``-``66``, ``93``, ``-``11``]`     `# Using numpy to print the negative number` `temp ``=` `np.array(list1)` `neg_nos ``=` `temp[temp <``=` `0``]`   `print``(``"Negative numbers in the list: "``, ``*``neg_nos)`

Output:

`Negative numbers in the list:  -10 -45 -66 -11`

## Python3

 `#Recursive function to check current element negative or not` `def` `PrintNegative(itr,list1):` `  ``if` `itr ``=``=` `len``(list1): ``#base condition` `    ``return` `  ``if` `list1[itr] < ``0``: ``#check negative number or not` `    ``print``( list1[itr],end ``=` `" "``)` `  ``PrintNegative(itr``+``1``,list1) ``#recursive function call` `  `  `list1 ``=` `[``-``1``,``8``,``9``,``-``5``,``7``]` `PrintNegative(``0``,list1)`

Output

`-1 -5 `
