Print list of lists in separate lines
I have a list of lists:
a = [[1, 3, 4], [2, 5, 7]]
I want the output in the following format:
1 3 4 2 5 7
I have tried it the following way , but the outputs are not in the desired way:
for i in a: for j in i: print(j, sep=' ')
1 3 4 2 5 7
While changing the print call to use
for i in a: for j in i: print(j, end = ' ')
1 3 4 2 5 7
Iterate through every sub-list in your original list and unpack it in the print call with
a = [[1, 3, 4], [2, 5, 7]] for s in a: print(*s)
The separation is by default set to
' ' so there's no need to explicitly provide it. This prints:
1 3 4 2 5 7
In your approach you were iterating for every element in every sub-list and printing that individually. By using
print(*s) you unpack the list inside the print call, this essentially translates to:
print(1, 3, 4) # for s = [1, 2, 3] print(2, 5, 7) # for s = [2, 5, 7]
Print lists in Python (4 Different Ways), 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 a = [1, 2, 3, 4, 5] # printing the list using loop. for x in range(len(a)): print a [x], chevron_right. filter_none. Output: 1 2 3 4 5. Without using loops: * symbol is use to print the list elements in a single line with space.
print('\n'.join(' '.join(map(str,sl)) for sl in l))
you can convert
str by using join function:
l = ['1','2','3'] ' '.join(l) # will give you a next string: '1 2 3' '.'.join(l) # and it will give you '1.2.3'
so, if you want linebreaks you should use new line symbol.
But join accepts only list of strings. For converting list of things to list of strings, you can apply
str function for each item in list:
l = [1,2,3] ' '.join(map(str, l)) # will return string '1 2 3'
And we apply this construction for each sublist
sl in list
How to print a list of lists in columns in Python, How to print a list of lists in columns in Python. Printing a list of lists in columns creates output that resembles a table, with list elements representing rows. for column, val in enumerate(row): if headers [column] in ['Incorrect name value', 'Address included', 'Telephone number present', 'Move completed'] and val == 'True': failed_validation_lst.append (headers [column]) failed_validation_string = '; '.join (failed_validation_lst) print(failed_validation_string) Find.
You can do this:
>>> lst = [[1, 3, 4], [2, 5, 7]] >>> for sublst in lst: ... for item in sublst: ... print item, # note the ending ',' ... print # print a newline ... 1 3 4 2 5 7
Printing Lists Using Python, Type the following code into the notebook — pressing Enter after each line: to unpack the list and send each element to the print() method one item at a time. The sep argument tells how to separate each of the printed outputs, relying on a Printing list elements on separated lines in Python - Stack Overflow. I am trying to print out Python path folders using this:import sysprint sys.pathThe output is like this:>>> print sys.path['.', '/usr/bin', '/home/student/Desktop', '/home/student/. Stack Overflow.
def print_list(s): for i in range(len(s)): if isinstance(s[i],list): k=s[i] print_list(k) else: print(s[i]) s=[[1,2,[3,4,[5,6]],7,8]] print_list(s)
you could enter lists within lists within lists ..... and yet everything will be printed as u expect it to be.
Python : Convert list of lists or nested list to flat list – thispointer.com, In this article we will discuss different ways to convert a list of lists or nested lists to a single flat list. item in elem]. print('Flat List : ', flatList) Although this is a single line solution but this kind of coding is not easy to maintain. for item in l: print(str(item[0:]) [1:-1]) where l is your list. For your input, this prints out: tables 1, 2 ladders 2, 5 chairs 2. Another (cleaner) way would be something like this: for item in l: value_set = str(item[0:]) print (value_set[1:-1]) Yields the same output: tables 1, 2 ladders 2, 5 chairs 2.
Storing Multiple Values in Lists – Programming with Python, for number in odds: print(number). 1 3 5 7. There is one important difference between lists and strings: we can change the values in a list, but we cannot change Type the following code into the notebook — pressing Enter after each line: Colors = ["Red", "Orange", "Yellow", "Green", "Blue"] print (*Colors, sep=' ') You use a for loop to print the individual items. This example takes another approach.
Loops and lists, Our table data have so far used one separate list for each column. For example, a long list like our table variable, demands a quite long line when printed. Given a nested 2D list, the task is to split the nested list into two lists such that first list contains first elements of each sublists and second list contains second element of each sublists. Method #1: Using map, zip()
Lists, Unlike strings, lists are mutable because you can change the order of items in a list Each debug line is printing the list of words which we get when we split the Print a dictionary line by line using for loop & dict.items() dict.items() returns an iterable view object of the dictionary that we can use to iterate over the contents of the dictionary, i.e. key-value pairs in the dictionary and print them line by line i.e.
