Python print new line with variable

When I use "\n" in my print function it gives me a syntax error in the following code

from itertools import combinations
a=[comb for comb in combinations[range[1,96+1],7] if sum[comb] == 42]
print [a "\n"]

Is there any way to add new line in each combination?

The print function already adds a newline for you, so if you just want to print followed by a newline, do [parens mandatory since this is Python 3]:

print[a]

If the goal is to print the elements of a each separated by newlines, you can either loop explicitly:

for x in a:
    print[x]

or abuse star unpacking to do it as a single statement, using sep to split outputs to different lines:

print[*a, sep="\n"]

If you want a blank line between outputs, not just a line break, add end="\n\n" to the first two, or change sep to sep="\n\n" for the final option.

Two possibilities:

print "%s\n" %a
print a, "\n"

This will work for you:

I used 1,2...6 in my example and 2 length tuples with a combination sum of 7.

from itertools import combinations
a=["{0}\n".format[comb] for comb in combinations[range[1,7],2] if sum[comb] == 7]

print[a]
for thing in a:
    print[thing]

Output

['[1, 6]\n', '[2, 5]\n', '[3, 4]\n']
[1, 6]

[2, 5]

[3, 4]

for me in the past something like print["\n",a] works.

Print new line after a variable in Python #

Use the addition operator to print a new line after a variable, e.g. print[variable + '\n']. The newline [\n] character is a special character in python and is used to insert new lines in a string.

Copied!
# ✅ Print new line after variable
variable = "bobby"

my_str = variable + '\n' + 'hadz'

# bobby
# hadz
print[my_str]

# ----------------------------------

# ✅ Print new line after each item in list of strings

# 👇️ print items of list of strings on separate lines
my_list = ['bobby', 'hadz', 'com']

result = '\n'.join[my_list]

# bobby
# hadz
# com
print[result]

# ----------------------------------

# ✅ Print new line after each item in list of integers

my_list = [2, 4, 8]

result = '\n'.join[str[num] for num in my_list]

# 2
# 4
# 8
print[result]

The first example uses the addition [+] operator to print a new line after a variable.

Copied!
variable = "bobby"

my_str = variable + '\n' + 'hadz'

# bobby
# hadz
print[my_str]

If the variable is not of type string, pass it to the str[] class before using the addition operator.

Alternatively, you can use a formatted string literal.

Copied!
variable = "bobby"

my_str = f'{variable}\nhadz'

# bobby
# hadz
print[my_str]

Formatted string literals [f-strings] let us include expressions inside of a string by prefixing the string with f.

Make sure to wrap expressions in curly braces - {expression}.

When using a formatted string literal, you don't have to convert the value stored in the variable to a string as this is done for us automatically.

If you need to print a new line after each item in a list, use the str.join[] method to join the list with a newline [\n] character separator.

Copied!
my_list = ['bobby', 'hadz', 'com']

result = '\n'.join[my_list]

# bobby
# hadz
# com
print[result]

The str.join method takes an iterable as an argument and returns a string which is the concatenation of the strings in the iterable.

Note that the method raises a TypeError if there are any non-string values in the iterable.

If your iterable contains numbers or other types, convert all of the values to strings before calling join[].

Copied!
my_list = [2, 4, 8]

result = '\n'.join[str[num] for num in my_list]

# 2
# 4
# 8
print[result]

The string the method is called on is used as the separator between the elements.

Alternatively, you can use a for loop to iterate over the list and print each item.

Copied!
my_list = ['bobby', 'hadz', 'com']

for item in my_list:
    # bobby
    # hadz
    # com
    print[item]

By default, the print[] function prints a newline character at the end of each message.

You can change this behavior by setting the end argument in the call to print[].

Copied!
print['a', 'b', 'c']  # 👉️ 'a b c\n'

print['a', 'b', 'c', end='']  # 👉️ 'a b c'
