python and bidirectional hit

Question

[v27]

i have written a program to detect the bidirectional hit. which is as follows

query = open("abc.txt","r").readlines()
database = open("cba","r").readlines()

Q2Ddict = {}
for line in query:
Q2Ddict[line.rsplit()[0]] = line.rsplit()[1]

D2Qdict = {}
for line in database:
#print(line.rsplit()[0],line.rsplit()[1])
D2Qdict[line.rsplit()[0]] = line.rsplit()[1]

for qtd,dbs in Q2Ddict.items():
for dbq,qts in D2Qdict.items():
if(qtd == qts and dbs == dbq):
print(qtd,dbs)

and the output generated is :

WP_003691339.1 WP_003691339.1
WP_010360713.1 WP_010360713.1
WP_003690758.1 WP_003690758.1
WP_003688953.1 WP_003688953.1
WP_047916891.1 WP_012503426.1
WP_002244992.1 WP_002244992.1
WP_003688378.1 WP_010356285.1

the problem is : that after every a new line is being inserted. (to remove that in perl there is a command chomp). how and where to use a similar command in python?

I don't know if I understand your question, but print() will put a new line at the end unless you tell it not to (print(, end="")). What's your desired output?

The print function has an argument that you can use

print("something", end = "")

end can be any char or scape char

Try the .rstrip() method
