import pandas as pd
import locale
from locale import atof

df = pd.DataFrame([['1,200', '4,200'], ['7,000', '-0.03'], ['5', '0']])
#        0      1
# 0  1,200  4,200
# 1  7,000  -0.03
# 2      5      0
locale.setlocale(locale.LC_NUMERIC, '')
df.applymap(atof)
#         0        1
# 0  1200.0  4200.00
# 1  7000.0    -0.03
# 2     5.0     0.00
