Numeric value as a string and convert to actual numeric - python-3.x

Question

I found this thread how to make a variable change from the text "1m" into "1000000" in python
My string values are in a column within a pandas dataframe. The string/0bkects values are like 18M, 345K, 12.9K, 0, etc.
values = df5['Values']
multipliers = { 'k': 1e3,
'm': 1e6,
'b': 1e9,
}
pattern = r'([0-9.]+)([bkm])'
for number, suffix in re.findall(pattern, values):
number = float(number)
print(number * multipliers[suffix])
Running the code gives this error:
Traceback (most recent call last):
File "c:/Users/thebu/Documents/Python Projects/trading/screen.py", line 19, in <module>
for number, suffix in re.findall(pattern, values):
File "C:\Users\thebu\Anaconda3\envs\trading\lib\re.py", line 223, in findall
return _compile(pattern, flags).findall(string)
TypeError: expected string or bytes-like object
Thanks

Here's another way using regex:
import re
def get_word(s):
# find word
r = re.findall(r'[a-z]', s)
# find numbers
w = re.findall(r'[0-9]', s)
if len(r) > 0 and len(w) > 0:
r = r[0]
v = multipliers.get(r, None)
if v:
w = int(''.join(w))
w *= v
return round(w)
df['col2'] = df['col'].apply(get_word)
print(df)
col col2
0 10k 10000
1 20m 20000000
Sample Data
df = pd.DataFrame({'col': ['10k', '20m']})
