Printing a list in python can be done is following ways:

• Using for loop : Traverse from 0 to len(list) and print all elements of the list one by one using a for loop, this is the standard practice of doing it. 

Python

a = [1, 2, 3, 4, 5]

for x in range(len(a)):

    print a[x],

• Without using loops: * symbol is use to print the list elements in a single line with space. To print all elements in new lines or separated by space use sep=”\n” or sep=”, ” respectively. 

Python

a = [1, 2, 3, 4, 5]

print(*a)

print("printing lists separated by commas")

print(*a, sep = ", ") 

print("printing lists in new line")

print(*a, sep = "\n")

Output

1 2 3 4 5
printing lists separated by commas
1, 2, 3, 4, 5
printing lists in new line
1
2
3
4
5

• Convert a list to a string for display : If it is a list of strings we can simply join them using join() function, but if the list contains integers then convert it into string and then use join() function to join them to a string and print the string. 

Python

a =["Geeks", "for", "Geeks"]

print(' '.join(a))

a = [1, 2, 3, 4, 5]

print str(a)[1:-1] 

Output

Geeks for Geeks
1, 2, 3, 4, 5

• Using map : Use map() to convert each item in the list to a string if list is not a string, and then join them: 

Python

a = [1, 2, 3, 4, 5]

print(' '.join(map(str, a))) 

print"in new line"

print('\n'.join(map(str, a)))

Output

1 2 3 4 5
in new line
1
2
3
4
5

• Using list comprehension : Use list comprehension to go one by one to each element in list and print. 

Python3

a = [1, 2, 3, 4, 5]

[print(i, end=' ') for i in a] 

print("\nIn new line")

[print(i) for i in a]

Output

1 2 3 4 5 
In new line
1
2
3
4
5
