please explain “my_string” variable.
how does it works .
explain line by line
Python basics-2 about string
You are requested to give the line at moment where you are unable to understand it since my_string changes thrice or more times in the video.
i think it happened at 4:07,how " % " work before parenthesis.
So generally we can use %operator in a string followed by the datatype and than at end of string we again add % followed by all the data variables.
Example:
a = int(5)
b = “random_string”
c = (“I just generated %s and one random number %d” % (b,a))
Now c will contain = I just generated random_string and one random number 5
