I want to increment the variable inside the print statement, so it would not take 2 lines of code.

I have the following code:

yearCount += 1    
print("Year ",yearCount,":",sep = "")

How can I do something like:

print("Year",yearCount+=1,":",sep = "")

For printing only, you can use f-strings, available in v3.6+:

print(f'Year {yearCount+1}:')

If you also need to increment the variable itself, I would stick with the two-liner; it's best to be clear and differentiate between calculations and printed output.


A not recommended answer to your question would be:

yearCount += 1; print(f'Year {yearCount}:')

Remember when we saw variables and the assignment operator =. length = 4 width = 6 area = length * width # area of a rectangle print(area) # will output 24 Python knows how to add integers, and it can replace this sum of two integers  The object is an instance of int having value 1 and the name a refers to it. The assigned name a and the object to which it refers are distinct. Now lets increment a. >>> a +=1 >>> print(id(a)) 1919375104 >>> print(hex(id(a))) 0x72675700. As int are immutable, python understand above statement as.

Use format to format the string for printing and not actually incrementing the value

print("Year {}".format(yearCount+1))

If you're familiar with Python, you would have known Increment and Decrement operators ( both pre and post) are not allowed in it. Python is for variable_name in range(start, stop, step) An integer number specifying the incrementation. print (i). # this is for increment operator here start = 5,. # stop = -1 and step = -1. Increment and Decrement Operators in Python If you’re familiar with Python, you would have known Increment and Decrement operators ( both pre and post) are not allowed in it. Python is designed to be consistent and readable.

You can go through official doc for print function Documentation.

 a = 2
 print("Sum is :", a+3)

output is :

 Sum is :5

The output of this program is 5 7, because the first time bruce is printed, his value In Python, an assignment statement can make two variables equal, but they Updating a variable by adding 1 is called an increment; subtracting 1 is called a function counts the number of decimal digits in a positive integer expressed in​  Note: print() was a major addition to Python 3, in which it replaced the old print statement available in Python 2. There were a number of good reasons for that, as you’ll see shortly. Although this tutorial focuses on Python 3, it does show the old way of printing in Python for reference.

It is not possible to initialize variable(s) within print(). The best thing that you could do is call a function via f-string. Use that called function to increment the variable that you want.

yearCount = 2018
def yearInc():
  global yearCount
  yearCount+=1
  return yearCount

print(f"Year {yearInc()}")
print(f'Year {yearCount}')

The output is:

Year 2019
Year 2019

This solution may be wasteful if you just to call this function once.

print (a). 111. >>> b = 'Hello'. >>> b + = 1. Traceback (most recent call last): We have incremented the integer variable a in successive steps here. Also, since the + The option of not including the ++ operator in Python is a design decision. In Python, you can increase the value of a variable by 1 or reduce it by 1 using the augmented assignment operators. The code spam += 1 and spam -= 1 increments and decrements the numeric values in spam by 1 , respectively.

In this article, you'll learn about the global keyword, global variable and when to use When we run the above program, the output shows an error: c = 0 # global variable def add(): global c c = c + 2 # increment by 2 print("Inside add():",​  Python While loop will check for the condition at the beginning of the loop. If the condition is True then it will execute the code inside the loop. Next we have to use Arithmetic Operator inside the Python while loop to increment and decrements the value. After the value incremented it will again check the condition.

Now let us understand the concept of range function() in python, below There are three parameters inside the range(): start, stop, and step. Step: Optional — An integer number that specifies how much to increment the number we put the range function in a for loop. x = range(10) for i in x: print(i)0 1 2 The <statement(s)> in the loop body are denoted by indentation, as with all Python control structures, and are executed once for each item in <iterable>. The loop variable <var> takes on the value of the next element in <iterable> each time through the loop.

Understanding Java loops, starting with the for loop. int addition = 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10; This is called the increment number, and is usually 1. Whatever is currently inside of the loopVal variable will be printed out, along with Microsoft Word · Microsoft Excel · PHP for Beginners · Python for Beginners  print ("The incremented character value is : ",end="") The incremented character value is : P. Explanation : ord () returns the corresponding ASCII value of character and after adding integer to it, chr () again converts it into character. Using byte string. # python code to demonstrate way to. # increment character. # initializing byte character.

  • Less lines aren't automatically better. By shoving side effects into a print, you're obscuring the control flow and making your code harder to read.
