Alright, I know how to print variables and strings. But how can I print something like \"My string\" card.price (it is my variable). I mean, here is my code:
print \"
'''
If the python version you installed is 3.6.1, you can print strings and a variable through
a single line of code.
For example the first string is "I have", the second string is "US
Dollars" and the variable, **card.price** is equal to 300, we can write
the code this way:
'''
print("I have", card.price, "US Dollars")
#The print() function outputs strings to the screen.
#The comma lets you concatenate and print strings and variables together in a single line of code.
From what I know, printing can be done in many ways
Here's what I follow:
Printing string with variables
a = 1
b = "ball"
print("I have", a, b)
Versus printing string with functions
a = 1
b = "ball"
print("I have" + str(a) + str(b))
In this case, str() is a function that takes a variable and spits out what its assigned to as a string
They both yield the same print, but in two different ways. I hope that was helpful
By printing multiple values separated by a comma:
print "I have", card.price
The print statement will output each expression separated by spaces, followed by a newline.
If you need more complex formatting, use the ''.format() method:
print "I have: {0.price}".format(card)
or by using the older and semi-deprecated % string formatting operator.
If you are using python 3.6 and newer then you can use f-strings to do the task like this.
print(f"I have {card.price}")
just include f in front of your string and add the variable inside curly braces { }.
Refer to a blog The new f-strings in Python 3.6: written by Christoph Zwerschke which includes execution times of the various method.
All answers above are correct, However People who are coming from other programming language. The easiest approach to follow will be.
variable = 1
print("length " + format(variable))
Assuming you use Python 2.7 (not 3):
print "I have", card.price
(as mentioned above).
print "I have %s" % card.price
(using string formatting)
print " ".join(map(str, ["I have", card.price]))
(by joining lists)
There are a lot of ways to do the same, actually. I would prefer the second one.
