Python字符串

#什么是字符串？字符串是一系列字符，用引号括起来（单引号，双引号）

str1="这是字符串1"
str2=‘这是字符串2‘

name="Itester coco"
print(name.title())
#title()以首字母大写的方式显示每个单词（即每个首字母都改为大写）

print(name.upper())
print(name.lower())

#Python中使用 +来拼接字符串
first_name="ITester"
last_name="coco"
full_name=first_name+" "+last_name
print(full_name)

#拼接消息：个性化消息
first_name="ITester"
last_name="coco"
full_name=first_name+" "+last_name
msg="Hello,"+full_name.title()+"!"
print(msg)

#空白泛指任何非打印字符，如空格、制表符、换行符

print("\tpython")
print("Languages:\nPython\nJava\nC")
print("Languages:\n\tPython\n\tC\n\tJava\n\tPHP")

#暂时删除
msg="python php "
print(msg)
print(msg.rstrip())

#永久删除
msg="python php "
msg=msg.rstrip()
print(msg)

#删除左右两边的空白
msg=" pyhont php "
print(msg.strip())

#成对的单引号包含单引号
msg=‘ITester‘s coco‘
