I need to search for these lines / words and have them as the next data set

---AP_A data---
Name:AP_A
in-degA:0.0006766529737718963
out-degA:1.1814245426625214
---AP_B data---
Name:AP_B
in-degB:1.6025829114087657
out-degB:0.0006766529737718963

         search_words1=['Name:AP_A','in-degA','out-degA','Name:AP_B','in-degB','out-degB']
         for line in inputfile:
             if any(word in line  for word in search_words1):
                print("---datos_NodoA---")

                print("---datos_NodoB---")
                print(line)

thanks in advance

Answer 1

You know that you have data A and data B. You know that you get either a string with "AP_X" or "degX" from the lines you are interested in. Plus you want to print a flag to say which data you enter in.

Well, your data start with "Name:AP_X".

You set all "write" var for A and B to false. When you first meet "Name:AP_A", you turn write_A on, keep write_B off, print your header which will no be printed twice (cause only when write_A = False and "Name:AP_A" in line) and then you write the lines containing the labels of interest.

archivo_ficha= "ficha_nodos_triang28.txt"

with open(archivo_ficha,'r') as inputfile:

     write_A = False; write_B = False; out_list = []

     for line in inputfile:

         if 'AP_A' in line and write_A == False:
            out_list.append("---datos_NodoA---"); print (out_list[-1])
            write_A = True; write_B = False

         if write_A == True and 'AP_A' in line or 'degA' in line:
            out_list.append(line.strip()); print (out_list[-1])


         if 'AP_B' in line and write_B == False:
            out_list.append("---datos_NodoA---"); print (out_list[-1])
            write_B = True; write_A = False

         if write_B == True and 'AP_B' in line or 'degB' in line:
             out_list.append(line.strip()); print (out_list[-1])

     inputfile.close()

Output:

---datos_NodoA---
Name:AP_A
in-degA:0.0006766529737718963
out-degA:1.1814245426625214
---datos_NodoB---
Name:AP_B
in-degB:1.6025829114087657
out-degB:0.0006766529737718963
