Printing list in different columns - python-3.x

Question

I am quite new to Python and I am now struggling with printing my list in columns. It prints my lists in one columns only but I want it printed under 4 different titles. I know am missing something but can't seem to figure it out. Any advice would be really appreciated!
def createMyList():
myAgegroup = ['20 - 39','40 - 59','60 - 79']
mygroupTitle = ['Age','Underweight','Healthy','Overweight',]
myStatistics = [['Less than 21%','21 - 33','Greater than 33%',],['Less than 23%','23 - 35','Greater than 35%',],['Less than 25%','25 - 38','Greater than 38%',]]
printmyLists(myAgegroup,mygroupTitle,myStatistics)
return
def printmyLists(myAgegroup,mygroupTitle,myStatistics):
print(': Age : Underweight : Healthy : Overweight :')
for count in range(0, len(myAgegroup)):
print(myAgegroup[count])
for count in range(0, len(mygroupTitle)):
print(mygroupTitle[count])
for count in range(0, len(myStatistics)):
print(myStatistics[0][count])
return
createMyList()

To print data in nice columns is nice to know Format Specification Mini-Languag (doc). Also, to group data together, look at zip() builtin function (doc).
Example:
def createMyList():
myAgegroup = ['20 - 39','40 - 59','60 - 79']
mygroupTitle = ['Age', 'Underweight','Healthy','Overweight',]
myStatistics = [['Less than 21%','21 - 33','Greater than 33%',],['Less than 23%','23 - 35','Greater than 35%',],['Less than 25%','25 - 38','Greater than 38%',]]
printmyLists(myAgegroup,mygroupTitle,myStatistics)
def printmyLists(myAgegroup,mygroupTitle,myStatistics):
# print the header:
for title in mygroupTitle:
print('{:^20}'.format(title), end='')
print()
# print the columns:
for age, stats in zip(myAgegroup, myStatistics):
print('{:^20}'.format(age), end='')
for stat in stats:
print('{:^20}'.format(stat), end='')
print()
createMyList()
Prints:
Age Underweight Healthy Overweight
20 - 39 Less than 21% 21 - 33 Greater than 33%
40 - 59 Less than 23% 23 - 35 Greater than 35%
60 - 79 Less than 25% 25 - 38 Greater than 38%
