PYTHON(NOT JAVA) HELP!
THIS IS A3Q2 PYTHON CODE FOR GRAPHING:
The python code for the above question is:
#function to calculate the output value
def calc(t,r,p):
pt = float(r)*float(p)*(1-float(p))
return pt
#checking if time steps is a positive number
goodt=False
while not goodt:
try:
t = input('How many time steps to simulate ? : ')
if int(t)>0:
goodt=True
else:
print("Entered number is not a positive integer! Please try again.")
except ValueError:
print("Entered number is not a positive integer! Please try again.")
#checking if entered rate is a positive floating point number
goodr=False
while not goodr:
try:
r = input('What is the rate of change ? : ')
if float(r)>0:
goodr=True
else:
print("Entered number is not a positive floating point number! Please try again.")
except ValueError:
print("Entered number is not a positive floating point number! Please try again.")
#checking if entered starting population is between 0 and 1
goodp=False
while not goodp:
try:
p = input('What is the starting population ? : ')
if 0 goodp=True
break
else:
print("Entered number is not between 0 and 1! Please try again.")
except ValueError:
print("Entered number is not between 0 and 1! Please try again.")
time=int(t)
print("Time population ")
#time population between 0 to time entered
for i in range(0,time+1):
print(i," ",p)
p = calc(i,r,p)
i=i+1
Question 3 (6 points): Purpose: To learn some of the tools provided by a very practical and popular Python module. To practice Degree of Difficulty: The coding here is Easy.
