lambda pandas code example
Example 1: pandas apply function to each row lambda
def EOQ(D,p,ck,ch):
Q = math.sqrt((2*D*ck)/(ch*p))
return Q
ch=0.2
ck=5
df['Q'] = df.apply(lambda row: EOQ(row['D'], row['p'], ck, ch), axis=1)
df
Example 2: lambda in pandas
Series.apply(lambda x: x**2)
#x represent the cell value and x**2 is your function
Example 3: use apply with lambda pandas
df.apply(lambda x: func(x['col1'],x['col2']),axis=1)
