Interactive input/output

The command, raw_input(), asks a question, and displays what you answer.

print raw_input("What is your name? ")

$ What is your name? Megan $ Megan

The above can be arranged as follows:

name=raw_input("What is your name?") print "Hi %s. Nice to meet you." %name

$ What is your name? Megan $ Hi Megan. Nice to meet you.

Input() also takes numbers as a methematical value.

const=input("Input some number.") for i in range(3):   print "%d*%d=%d" %(const,i,i*const)

$ Input some number.5 $ 5*0=0 $ 5*1=5 $ 5*2=10
