您只需要评估df.A | df.B | df.C
.
df['OR_Gate'] = df.A | df.B | df.C
注意:如果 A、B、C 列中的值是 0 和 1 的字符串,则执行以下操作之一:
# Method-1:
# Convert the strings into int and then evaluate OR_Gate:
# This changes the value-types in the columns A, B, C
df = df.astype('int')
df['OR_Gate'] = df.A | df.B | df.C
# Method-2:
# This will not change the original data type in columns A, B, C
# But will correctly evaluate 'OR_Gate'.
df['OR_Gate'] = df.A.astype(int) | df.B.astype(int) | df.C.astype(int)
# Method-3:
# If you want your final output to be in boolean form.
df['OR_Gate'] = df.A.astype(bool) | df.B.astype(bool) | df.C.astype(bool)
详细解决方案
import pandas as pd
# Dummy data
A = [0]*4 + [1]*4
B = [0]*2 + [1]*2 + [0]*2 + [1]*2
C = [0, 1]*4
# Make Dataframe
df = pd.DataFrame({'A': A, 'B': B, 'C': C})
# Update 'OR_Gate' Output
df['OR_Gate'] = df.A | df.B | df.C
df
输出:
A B C OR_Gate
