Python program to print negative numbers in a list
In this article, we will learn about the solution and approach to solve the given problem statement.
Problem statement
Given a list iterable, we need to print all the negative numbers in the list.
Here we will be discussing three approaches for the given problem statement.
Approach 1 − Using enhanced for loop
Example
list1 = [-11,23,-45,23,-64,-22,-11,24] # iteration for num in list1: # check if num < 0: print(num, end = " ")
Output
-11 -45 -64 -22 -11
Approach 2 − Using filter & lambda function
Example
list1 = [-11,23,-45,23,-64,-22,-11,24]
# lambda exp.
no = list(filter(lambda x: (x < 0), list1))
print("Negative numbers in the list: ", no)Output
Negative numbers in the list: [-11 -45 -64 -22 -11]
Approach 3 − Using list comprehension
Example
list1 = [-11,23,-45,23,-64,-22,-11,24]
#list comprehension
nos = [num for num in list1 if num < 0]
print("Negative numbers in the list: ", nos)Output
Negative numbers in the list: [-11 -45 -64 -22 -11]
Conclusion
In this article, we learned about the approach to print negative numbers in the input list.
