Python: Extract numbers from a given string

Python String: Exercise-93 with Solution

Extract numbers from string.

Write a Python program to extract numbers from a given string.

Sample Solution:

Python Code:

# Define a function to extract numbers from a given string
def test(str1):
    # Use a list comprehension to extract integers from the string if they are digits
    result = [int(str1) for str1 in str1.split() if str1.isdigit()]
    
    # Return the list of extracted numbers
    return result

# Initialize a string containing a mix of words and numbers
str1 = "red 12 black 45 green"

# Print the original string
print("Original string:", str1)

# Print a message indicating the extraction of numbers from the string
print("Extract numbers from the said string:")
# Call the function to extract numbers and print the result
print(test(str1)) 

Sample Output:

Original string: red 12 black 45 green
Extract numbers from the said string:
[12, 45]
