String基本方法
test = " helloWord "
1单词全部大写stringObj.upper();
print("testtextUpper=(" + test.upper() + ")")
2单词全部小写stringObj.lower();
print("testTextLower=(" + test.lower() + ")")
3单词首字母大写stringObj.title();
print("testTexttitle=(" + test.title() + ") ")
4.去除空格stringObj.strip(),
print("testTexttitle=(" + test.title().strip() + ")")
4-1去左空格stringObj.lstrip();
print("testTextLower=(" + test.lower().lstrip() + ")")
4-2去右空格stringObj.rstript();
print("testtextUpperRstrip=(" + test.upper().rstrip() + ")")
二,str()方法与string,int互转
a='p' print (type (a)) >>>(class 'str') b=6 print(type (b)) >>>(class 'int') #string转int a2=int(a) print (type (a2)) >>>(class 'int') #int转string b2=int(b) print (type (b2)) >>>(class 'str')
