Python program to print negative numbers in a list
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 |

filter_none
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) |
chevron_right
filter_none
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) |
chevron_right
filter_none
Output:
Negative numbers in the list: -10 -45 -66 -11
