create data frame from file-CodePudding

can we create a data frame for the below input:

OP1.T1:OP2.V2
OP1.T1:OP2.V3
OP2.T3:OP2.V2
OP3.T1:OP1.V2

Code tried:

with open("TableView.txt") as f:
   
    for line in f:
        line = line.strip()
        #print(line)
        cols = line.split(':')
        my_params = (cols[0],cols[1])
        #print(my_params)
        df= pd.DataFrame(my_params)
        print(df)

i need them likebelow:


    BaseS   BASET   DEPS    DEPN
0   OP1     T1      OP2    v2
1   OP1     T1      OP2    v3
2   OP2     T3      OP2    v2
3   OP3     T1      OP1   v2

CodePudding user response：

Use pandas.read_csv, you can specify \.|: as separator, which separates on either . or ::

from io import StringIO
s = StringIO('''OP1.T1:OP2.V2
OP1.T1:OP2.V3
OP2.T3:OP2.V2
OP3.T1:OP1.V2''')

df = pd.read_csv(s, sep='\.|:', header=None, names=['BaseS', 'BaseT', 'DEPS', 'DEPN'])

df

  BaseS BaseT DEPS DEPN
0   OP1    T1  OP2   V2
1   OP1    T1  OP2   V3
2   OP2    T3  OP2   V2
3   OP3    T1  OP1   V2
