Assumptions: 1) You actually meant to have commas between each key value pair (which your example DOES NOT have).
2) File can be read into memory
3) All the key and value variables are actually defined in the local namespace or they are literal values instead of references to variables.
This works:
Key11=11 Value11='V11' Key12=12 Value12='12' Key13=13 Value13='V13' Key21=21 Value21='V21' Key22=22 Value22='V22' Key23=32 Value23='V23' Key31=31 Value31='V31' Key32=32 Value32='V32' Key33=33 Value33='V33'
testdata='''
{Key11: Value11,\n
Key12: Value12,\n
Key13: Value13}\n
{Key21: Value21,\n
Key22: Value22,
Key23: Value23}\n
{Key31: Value31,\n
Key32: Value32,\n
Key33: Value33}\n
'''
#
# Or read data from a file
#
# f=open(file, 'r')
# testdata=f.read()
# f.close()
#
dictlist=testdata.replace('\n','').split('{')
firstdictstr='{'+dictlist[2]
lastdictstr='{'+dictlist[-1]firstdict=eval(firstdictstr) lastdict=eval(lastdictstr)
print "firstdict=", firstdict print "lastdict=", lastdict firstdict=eval(firstdictstr) lastdict=eval(lastdictstr)

In a file there can be several dictionaries like this {Key11: Value11 Key12: Value12 Key13: Value13, ... ... Key1n:Value1n} {Key21: Value21 Key22: Value22 Key23: Value23, ... ... Key2n:Value2n} {Key31: Value31 Key32: Value32 Key33: Value33, ... ... Key3n:Value3n} .... .... .... {Keyn1: Valuen1 Keyn2: Valuen2 Keyn3: Value3, ... ... Keynn:Valuenn}
Each pair in a dictionary is separated by CRLF and in each dictionary numbers of pairs can be different. I need to read only the the first and the last dictionaries.What is a best solution? Thanks Lad
