Python Beginner Question on comma Behaviour-CodePudding

I wrote the following program:

print ("Mom the food was good:"),
print ("Yummy"* 3)

Based on Python Programming Micheal Dawson the expected result is,

Mom the food was good:YummyYummyYummy

where as the result I get is :

Mom the food was good:

YummyYummyYummy

Why isn't the comma between the 2 prints not suppressing the newsline?

Why isn't the comma between the 2 prints not suppressing the newsline?

Because that was a feature of the Python 2 print statement. Python 3 (which you should be learning) no longer has a print statement, print is a function, and the commas cannot act like this. Essentially,

print(something),

is a tuple literal, evaluating to (None,)

In Python 3, the print function accepts sep=' ' and end='\n' keyword arguments (the defaults shown), which can be used to control this behavior:

print("Hello ", end="")
print("World")

Or:

print("everything", "on", "it's", "own", "line", sep="\n")

CodePudding user response：

print has '\n' in the end,you can use print("hello",end="")

CodePudding user response：

The comma between the operators "print" does not concatenate them. To write code that prints a message in one line, you need to use optional operator "end"

    print ("Mom the food was good:", end='')
    print ("Yummy" * 3)

Output:

    Mom the food was good:YummyYummyYummy
