Question

[Python]

I have the following function that removes all non-numerical characters from a string:

def remove_non_numeric(s):
  
seq_type= type(s)
return seq_type().join(filter(seq_type.isdigit, s))

And I need help implementing it into this function:

def list_only_numbers( a_list ) :

# Create a new empty list.

# Using a loop (or a list comprehension)

# 1) call remove_non_numeric with a list element

# 2) if the return value is not the empty string, convert

# the string to either int or float (if it contains a decimal

# point) and append the value to the new list.

# 3) if the return value is the empty string, do not

# append anything to the new list.

# Return the new list.

Answer 1

def list_only_numbers (a_list):
#Create a new list
l = []
n = 0

#USing a loop
for i in a_list:

#Call remove_non_numeric
s = remove_non_numeric (a_list[i])

#If the return value is not the empty string
if (s != ''):
#if there is a decimal in the string then convert it to float
if ('.' in s):
n = float(s)
#else convert it to integer
else:
n = int(s)
l.append(n)
return l
  

def list_only_numbers (a list) #create a new list #04ing a loop for i in a list: #Call remove non numeric s - remove non numeric (a list [i]) #If the return value is not the empty string #if there is a decimal in the string then convert it to float if 'in s) n -float (s) #else convert it to integer else: n = int (3) 1 . append (n) return 1
