python-4.文本,文本结合

exercise 6 文本格式化

在python里面,一切都是对象,对象拥有很多属性和方法.例如字符串就有format方法,传递参数到占位符. 连接两个字符串用’+’ print(x,y)这样的话x和y之间会有一个空格.

types_of_people = 10x=f"There are {types_of_people} types of people."binary = "binary"do_not="don't"y=f"Those who know {binary} and those who {do_not}."print(x)print(y)print(f"I said: {x}")print(f"I also said:'{y}'")print(x + y)hilarious=Falsejoke_evaluation = "Is't that joke so funny?! {}"print(joke_evaluation.format(hilarious))w="This is the left side of..."e="a string with a right side."print(w + e)

exercise 7 改变print结束符

print("Marry had a little lamb.")print("Its fleece was white as {}.".format('snow'))print("And everywhere that Mary went.")print("." * 10) # what'd that do?end1 = "C"end2 ="h"end3="e"end4="e"end5="s"end6="e"end7="B"end8="u"end9="r"end10="g"end11="e"end12="r"# watch end='' at the end. Try removing it to see what happensprint(end1+end2+end3+end4+end5+end6,end=' ')# print(end1+end2+end3+end4+end5+end6,end=' ')print(end7+end8+end9+end10+end11+end12)
