In this example, I have shared how to find all the numbers in a string using regular expression in Python. The parameters to these function are the pattern which we want to extract and the string from which we want to extract. Please note with below example we get only the digits and not the decimal points or the negative signs.
str=input("Enter a String with numbers: \n")
#Create a list to hold the numbers
num_list = re.findall(r'\d+', str)
Enter a String with numbers:
Go to 13.8 miles and then -4.112 miles.
['13', '8', '4', '112']
