[Python] Not able to read .txt file in iGraph python

I'm trying to read a text file containing space separated columns using python's python-igraph library. I'm following the documentation but still getting the following error.

Traceback (most recent call last):
File "C:/Users/Lucy/PycharmProjects/CS286Project/dataClean.py", line 3, in
<module>
read_graph= Graph.Read_Ncol('1.txt', directed=True)
NameError: name 'Graph' is not defined


Python code..

import igraph
read_graph = Graph.Read_Ncol('1.txt', directed=True)


.txt file

Since the spacing between columns is uneven, is that what is causing this error?

Edit 1:

After using the solution provided by @Gwendal Grelier I get the following error

read_graph = igraph.Graph.Read_Ncol('1.txt', directed=True)
igraph._igraph.InternalError: Error at src\foreign.c:243: Parse error in NCOL file, line 1 (syntax error, unexpected ALNUM, expecting NEWLINE), Parse error
