本节课全是复习题,就是码字码字码字,体验一下码农的感觉!!!
基础练习:
print("让我们把所有的东西都练习一下")
print('You\'d need to know \'bout escapes with \\ that do:')
print('\n newlines and \t tabs.')
poem = '''
\tThe lovely world
with logic so firmly planted
cannot discern \n the needs of love
nor comprehend passion from intuition
and requires an explanation
\n\t\twhere there is none.
'''
print("----------------------------------------")
print(poem)
print("----------------------------------------")
five = 10 - 2 + 3 - 6
print(f"This should be five: {five}")
def secret_formula(started):
jelly_beans = started * 500
jars = jelly_beans / 1000
crates = jars /100
return jelly_beans, jars, crates
start_point = 10000
beans, jars, crates = secret_formula(start_point)
# remember that this another way to format a string
print("With a starting point of:{}".format(start_point))
# It's just like with an f"" string
print(f"We'd have {beans} beans, {jars} jars, and {crates} crates.")
start_point = start_point / 10
print("We can also do that this way:")
formula = secret_formula(start_point)
# This is an easy way to apply a list to a format string
print("We'd have {} beans, {} jars, and {} crates.".format(*formula))
结果:
主要是练习之前学过的东西,看看忘记了多少?
