I am a beginner to Data Analysis using Python and stuck on the following:
I want to find maximum value from individual columns (pandas.dataframe) using Broadcasting /Vectorization methodology.
A snapshot of my data Frame is as follows:enter image description here
you can use pandas.DataFrame built-in function max and min to find it
example
df = pandas.DataFrame(randn(4,4))
df.max(axis=0) # will return max value of each column
df.max(axis=0)['AAL'] # column AAL's max
df.max(axis=1) # will return max value of each row
or another way just find that column you want and call max
df = pandas.DataFrame(randn(4,4))
df['AAL'].max()
df['AAP'].min()
min is the same
