Fix Python – How can I print variable and string on same line in Python?

Question

Asked By – Bob Uni

I am using python to work out how many children would be born in 5 years if a child was born every 7 seconds. The problem is on my last line. How do I get a variable to work when I’m printing text either side of it?

Here is my code:

currentPop = 312032486
oneYear = 365
hours = 24
minutes = 60
seconds = 60

# seconds in a single day
secondsInDay = hours * minutes * seconds

# seconds in a year
secondsInYear = secondsInDay * oneYear

fiveYears = secondsInYear * 5

#Seconds in 5 years
print fiveYears

# fiveYears in seconds, divided by 7 seconds
births = fiveYears // 7

print "If there was a birth every 7 seconds, there would be: " births "births"

Now we will see solution for issue: How can I print variable and string on same line in Python?


Answer

Use , to separate strings and variables while printing:

print("If there was a birth every 7 seconds, there would be: ", births, "births")

, in print function separates the items by a single space:

>>> print("foo", "bar", "spam")
foo bar spam

or better use string formatting:

print("If there was a birth every 7 seconds, there would be: {} births".format(births))

String formatting is much more powerful and allows you to do some other things as well, like padding, fill, alignment, width, set precision, etc.

>>> print("{:d} {:03d} {:>20f}".format(1, 2, 1.1))
1 002             1.100000
  ^^^
  0's padded to 2

Demo:

>>> births = 4
>>> print("If there was a birth every 7 seconds, there would be: ", births, "births")
If there was a birth every 7 seconds, there would be:  4 births

# formatting
>>> print("If there was a birth every 7 seconds, there would be: {} births".format(births))
If there was a birth every 7 seconds, there would be: 4 births
