Python >>>first="John">>>last="Doe">>>print(first,last,end="!")John Doe!>>> In this example, you’ve replaced the default newline end character with an exclamation mark. Notice how this breaks the usual neat way that callingprint()drops you into a new empty line. Now you get to...

In the above example, theprint()statement only includes theobjectto be printed. Here, the value forendis not used. Hence, it takes the default value'\n'. So we get the output in two different lines. Example 2: Python print() with end Parameter # print with end whitespaceprint('Good ...

[转帖]python中input()、print()用法 1.input()函数常涉及的强制类型转换 第一种是在键入时进行转换,例如:a = int(input()) 1 a=int (input()) 2 b=int (input()) 3 a=a +b 4 print (a) 1. 2. 3. 4. 第二种则是在使用时进行转换。这样赋值的数据存储的形式仍是input()返回的字符串类型...
