ok thank you, but there is a problem. I would like to set a for column 1 and b for column 2 with the use of pandas library.
Which command should I use? I tried

import pandas as pd

filename = 'input_text.txt'
df = pd.read_csv(filename, sep='\t',usecols=[0,1])
print(df)
a = df.column[1]

but no use...

I use command
open(7,file='testdata.txt',status='old')

It is no use?
testdata.txt is my input file

I would like to check if the commands of my code read my data of my input file. But this code show one 1x1 column with zeros (0) and do not show the data of the first column of my input file

The problem is that I have a file with 14 columns and 644 lines. I use these commands but my .exe file does not showing what I would like

I give you my code:
parameter (len=644) ! lines
dimension A(len,14) !rows
C real IMM, lat, lon
character header*110,Var1(len)*4,Var2(len)*8,Var3(len)*8
+ ,Var4(len)*8,Var5(len)*8,Var6(len)*8,Var7(len)*8,Var8(len)*8,Var9(len)*8,
+ ,Var10(len)*8, Var11(len)*8,Var12(len)*8,Var13(len)*8,Var14(len)*8,header_append*97
open(7,file='testdata.txt',status='old')
open(8,file='EX-1.out',status='unknown')

do i=1,len
write(*,5) A(i,1)
end do

5 format(2x,f3.1)

do i=1,ip
write(*,5) A(i,1)
end do

stop
end

Could you please help me?

ok thank you, but the point is that the first line in my file includes three values separated with comma (,) (i.e. 1,2,3 etc.) In this case which commanmd should I use?

I know, but I am reading so much that I have confused. Could you please tell me what to in order to finish my code?

Member 14991075 12-Nov-20 11:56am View

I just did it

Member 14991075 12-Nov-20 11:05am View

This message refer to line
IA=3.66*log10(A(i)/66)+5.5 (line 14)

Member 14991075 12-Nov-20 10:47am View

ok, I tried this but it shows me:
NameError: name 'IA' is not defined (IA is the equation I show you in my code solution above)

Member 14991075 12-Nov-20 9:06am View

Excuse me , I have tried your solution but command window shows me:
TypeError: cannot do label indexing on <class 'pandas.core.indexes.range.rangeindex'=""> with these indexers [122.59] of <class 'float'="">
