Python基础复习与文件操作全解析

一、基础概念复习

在Python编程中，函数、循环、列表、字典和条件逻辑是非常基础且重要的概念。下面我们通过一个实例来复习这些基础内容。

首先，将以下代码复制到IDLE中，并保存为 fundamental_review.py ：

print "\n# -- part 1 -- #"
# Modify the variable value so that all of the
# `print` statements return `True`.
zero = 1
one = 2
two = [5, 4, 3, 2, 1, 0]
three = "I love Python!"
four = [["P", "y", "t", "h", "o", "n"],["i", "s"],["h", "a", "r", "d"]]
five = {"happy":"birthday"}
six = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
days = ("Fri", "Sat", "Sun")
x, y, seven = days
# DO NOT CHANGE ANYTHING BELOW THIS LINE #
# -------------------------------------- #
print("zero:  {}".format(zero == 0))
print("one:   {}".format(one > 22))
print("two:   {}".format(len(two) == 5))
print(
