I have a file with the following format.
>abc
qqqwqwqwewrrefee
eededededededded
dededededededd
>bcd
swswswswswswswws
wswswsddewewewew
wrwwewedsddfrrfe
>fgv
wewewewewewewewew
wewewewewewewxxee
wwewewewe
I was trying to create a dictionary with (>abc,>bcd,>fgv) as keys and the string below them as values. I could extract the keys but confused about updating the values. help me pls.
file2 = open("ref.txt",'r')
for line in file2.readlines():
if ">" in line:
print (line)
Not sure what you mean about "updating" the values, but try this:
mydict=[]
with open("ref.txt", "r") as file2:
current = None
for line in file2.readlines():
if line[0] == ">":
current = line[1:-1]
mydict[current] = ""
elif current:
mydict[current] += line # use line[:-1] if you don't want the '\n'
In [2]: mydict
Out[2]: {'abc': 'qqqwqwqwewrrefee\neededededededded\ndededededededd\n',
'bcd': 'swswswswswswswws\nwswswsddewewewew\nwrwewedsddfrrfe\n',
'fgv': 'wewewewewewewewew\nwewewewewewewxxee\nwwewewewe\n'}
When you get a line value with the '>' in it, save the line in a variable. When you read a line without the '>' in it, add it to a dictionary entry keyed by the previously saved variable.
key = None
dict = {}
for line in file2.readlines():
if ">" in line:
key = line
dict[key] = '' # Initialise dictionary entry
elif key is not None:
dict[key] += line # Append to dictionary entry
dictionary = {}
with open("file.txt","r") as r:
for line in r.readlines():
if ">" in line:
key = line[1:].strip()
dictionary[key] = ""
else:
dictionary[key] += line
print(dictionary)
d={}
key=''
file2 = open("ref.txt",'r')
for line in file2.readlines():
if line.startswith('>'):
key=line.strip()
d[key]=[]
continue
d[key].append(line.strip())
file.close()
I have not tested the above code, but it should work
