$ex33.py
i = 0
numbers = []
while i < 6:
print ("At the top i is %d" % i)
numbers.append(i)
i = i + 1
print ("Numbers now: ", numbers)
print ("At the bottom i is %d" % i)
print ("The numbers: ")
for num in numbers:
print (num)
print (numbers)
# from sys import argv
def printlist():
print ("Input a number:")
k = int(input ("Number:> "))
b = []
i = 0
while i < k:
b.append(i)
print (b[i])
i += 1
return b
print ("---" * 10)
print (printlist())
输出结果：
At the top i is 0
Numbers now: [0]
At the bottom i is 1
At the top i is 1
Numbers now: [0, 1]
At the bottom i is 2
At the top i is 2
Numbers now: [0, 1, 2]
At the bottom i is 3
