Print multiple variables in Python3

This post introduces several ways to print multiple arguments in python 3.

• Pass it as a tuple:

print("The cost for %s is %s" % (name, cost))

• Pass it as a dictionary:

print("The cost for %(n)s is %(c)s" % {'n': name, 'c': cost})

• Use the new-style string formatting:

print("the cost for {} is {}".format(name, cost))

• Use the new-style string formatting with numbers (useful for reordering or printing the same one multiple times):

print("The cost for {0} is {1}".format(name, cost))

• Use the new-style string formatting with explicit names:

print("The cost for {n} is {c}".format(n=name, c=cost))

• Pass the values as parameters and print will do it:

print("The cost for", name, "is", cost)

If you don’t want spaces to be inserted automatically by print in the above example, change the sep parameter:

print("The cost for ", name, " is ", cost, sep='')

• Use string concatenation

print("The cost for " + name + " is " + cost)

NOTE: If cost  is an int, then, you should convert it to str:

print("The cost for " + name + " is " + str(cost))

• Note that %s mentioned above can be replace by %d or %f.

If cost is a number, then

print("The cost for %s is %d" % (name, cost))

If cost is a string, then

print("The cost for %s is %s" % (name, cost))

If cost is a number, then it’s %d, if it’s a string, then it’s %s, if cost is a float, then it’s %f

• Use the new f-string formatting in Python 3.6:

print(f'The cost for {name} is {cost}')
