• Last Updated : 06 Jan, 2023

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

Example:

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

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

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

## Python3

 `# Python program to print positive 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 & gt``    ``=` `0``:``        ``print``(num, end``=``& quot``              ``& quot``              ``)`

Output:

`11 0 45 66 `

Example #2: Using while loop

## Python3

 `# Python program to print positive 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:

`21 93 `

Example #3: Using list comprehension

## Python3

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

Output:

`Positive numbers in the list:  45 93`

Example #4: Using lambda expressions

## Python3

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

Output:

`Positive numbers in the list:  21, 4, 93`

## Python3

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

Output

`[12, 5, 64]`

## Python3

 `# Python program to print positive 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``( ``not` `list2[i].startswith(``"-"``) ``and` `list2[i] !``=``"0"``):``        ``res.append(``str``(list1[i]))``res``=``" "``.join(res)``print``(res)`

Output

`11 45 66`

## Python

 `# Python program to print Positive Numbers in a List``import` `numpy as np``# list of numbers``list1 ``=` `np.array([``-``10``, ``-``21``, ``-``4``, ``45``, ``-``66``, ``93``])` `# using numpy Array``pos_nos ``=` `list1[list1 >``=``0``];` `print``(``"Positive numbers in the list: "``, ``*``pos_nos)`

Output:

`Positive numbers in the list:  45 93`

## Python3

 `#Function to print even numbers in a list``def` `PrintEven(itr,list1):``  ``if` `itr ``=``=` `len``(list1): ``#Base Condition``    ``return``  ``if` `list1[itr]>``=``0``:``    ``print``(list1[itr],end ``=` `" "``)``  ``PrintEven(itr``+``1``,list1)  ``#Recursive Function Call``  ``return` `list1 ``=` `[``-``5``,``7``,``-``19``,``10``,``9``] ``#list of numbers``PrintEven(``0``,list1) ``#Function Call` `#This code is contributed by vinay pinjala`

Output

`7 10 9 `
