Python program to print negative numbers in a list
• Difficulty Level : Basic
• Last Updated : 26 Oct, 2018

Given a list of numbers, write a Python program to print all negative numbers in 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 given list using for loop

Iterate each element in the list using for loop and check if number is less than 0. If the condition satisfies, then only print the number.

 `# 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

 `# 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

 `# 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

 `# 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`
