   a  b
0  1  1
1  2  0

Answer 1

You can convert Booleans to integers as follows:

df['b'] = df.b.astype(int)

Depending on the nature of your text in Column A, you can do a few things:

a) Split on the space and take the second part (either string or int depending on your needs).

df['a'] = df.a.str.split().str[1]  # Optional `.astype(int)`

b) Use regex to extract any digits (\d*) from the end of the string.

df['a'] = df.a.str.extract(r'(\d*)$')  # Optional `.astype(int)`
