Reading space separated input in Python
Here is the input specification:
The program has to read t lines of inputs. Each line consist of 2 space separated values first one is the name and second is the age.
An Example of开发者_StackOverflow社区 input:
Mike 18 Kevin 35 Angel 56
How to read this kind of input in Python? If I use raw_input()
, both name and age are read in the same variable.
the_string = input()
name, age = the_string.split()
In Python 2, use raw_input
instead of input
.
If you have it in a string, you can use .split()
to separate them.
>>> for string in ('Mike 18', 'Kevin 35', 'Angel 56'):
... l = string.split()
... print repr(l[0]), repr(int(l[1]))
...
'Mike' 18
'Kevin' 35
'Angel' 56
>>>
Assuming you are on Python 3, you can use this syntax
inputs = list(map(str,input().split()))
if you want to access individual element you can do it like that
m, n = map(str,input().split())
You can do the following if you already know the number of fields of the input:
client_name = raw_input("Enter you first and last name: ")
first_name, last_name = client_name.split()
and in case you want to iterate through the fields separated by spaces, you can do the following:
some_input = raw_input() # This input is the value separated by spaces
for field in some_input.split():
print field # this print can be replaced with any operation you'd like
# to perform on the fields.
A more generic use of the "split()" function would be:
result_list = some_string.split(DELIMITER)
where DELIMETER is replaced with the delimiter you'd like to use as your separator, with single quotes surrounding it.
An example would be:
result_string = some_string.split('!')
The code above takes a string and separates the fields using the '!' character as a delimiter.
For python 3 it would be like this
n,m,p=map(int,input().split())
For python 3 use this
inp = list(map(int,input().split()))
#input => java is a programming language
#return as => ("java","is","a","programming","language")
input() accepts a string from STDIN.
split()
splits the string about whitespace character and returns a list of strings.
map()
passes each element of the 2nd argument to the first argument and returns a map object
Finally list()
converts the map to a list
a=[]
for j in range(3):
a.append([int(i) for i in input().split()])
In this above code the given input i.e Mike 18 Kevin 35 Angel 56, will be stored in an array 'a' and gives the output as [['Mike', '18'], ['Kevin', '35'], ['Angel', '56']].
Space separated values inside an array with specific range:
arr = list(map(int, input().split()))[:n]
here n is denoting the maximum length of list.
For Python3:
a, b = list(map(str, input().split()))
v = int(b)
