using the output of a function as the input in another function python new to coding

Question:

# any help is greatly appreciated new to this stuff def total_bases(int1,int2,int3,int4): """(int, int, int, int) -> integer Return the total number of bases covered >>>total_bases(2,3,4,5) 40 """ return int1+2*int2+3*int3+4*int4 def slugging_percentage(total_bases,int5): """ (total_bases, int5) -> float # so for instance i need the product of the first function for the second function Return the slugging percentage given the total number of bases covered and the total number at bat(int5) >>>slugging_percentage(20,9) 2.22 """ return total_bases/int5 def on_base_percentage(h,bb,hbp,ab,sf): """(int,int,int,int,int) -> float Return the on-base percentage given the hits, base on balls, hit by pitch, at bats and sacrfice hits >>>on_base_percentage(1,2,3,4,5) 0.43 """ return (h+bb+hbp)/(ab+bb+hbp+sf) def on_base_plus_slugging(on_base_percentage,slugging_percentage): """(float,float) -> float # as well as for this Return the on-base plus slugging given the on-base percentage and the slugging percentage >>>on_base_plus_slugging(1.0,2.0) 3.0 """ return on_base_percentage+slugging_percentage def OPS_value(on_base_plus_slugging): """(float) -> string Return the on-base plus slugging value given the on-base plus slugging score range >>>OPS_value(0.8234) B """ if on_base_plus_slugging > 0.9000: return "A" elif on_base_plus_slugging > 0.7667: return "B" elif on_base_plus_slugging > 0.7000: return "C" else on_base_plus_slugging < 0.7000: return "F" elif on_base_plus_slugging == 0.7000: return "F"

Answer1:

Save the variable as global is one way.

def some_function(): global var #This is a global variable #Do things to variable

The other way, which is what I believe you are looking for is to call a function inside of a function. This would look like this:

def function_1(#some variable): #Stuff could be up here num = function2(5) #Stuff could be down here def function_2(a_number): a_number = a_number*2 return a_number

This will make the variable num = 5*2.

I hope this helps.

Answer2:

Functions can return values. You can store those values as variables. Then you can use those values as input to other functions.

I imagine you're trying to calculate the OPS_value using on_base and slugging percentages.

So you would calculate on_base, total_bases, and slugging and store the returned values in variables.

You then pass in those variables as input to your OPS_value function, which returns the final, calculated value.

<strong>See the below example:</strong>

def OPS_value(percent): """(float) -> string Return the on-base plus slugging value given the on-base plus slugging score range >>>OPS_value(0.8234) B """ if percent > 0.9000: return "A" elif percent > 0.7667: return "B" elif percent > 0.7000: return "C" else: return "F" total_bases = total_bases(2, 3, 4, 5) # Get the return value for total_bases slugging = slugging_percentage(total_bases, 9) # Get the return value for slugging_percent on_base = on_base_percentage(1, 2, 3, 4, 5) print OPS_value(on_base + slugging) # using on_base + slugging as input

What we're trying to do is keep the math related to calculating each thing total_bases, slugging, etc separate.

The other major change from your original code is that you don't need to have a function for just adding two values. <strong>You can and should do that in one line.</strong>
