Invoking function in if else statement, not working!

[ibaad1406]

I am invoking a function header_gps,header_glonass etc. in if else statement but the variables defined in there seem not be stored as they should be. May be i am missing something , please help. I am writing my code here itself.

"""Script for header section of rinex navigation file"""
from header_gps import header_gps
from header_glonass import header_glonass
from header_galileo import header_galileo
from header_beidou import header_beidou
def header(filepath):
    with open(filepath) as fp:
        data = fp.read()
        data=data.split("END OF HEADER")
        data=data[0]
        i=0
        while i>=0:
            if data[i]==' ':
                i=i+1
                continue
            else:
                break
        if data[i]=='2':
            print("Rinex_2")
        
            #Rinex_2
        elif data[i]=='3':
            print("Rinex_3")
            if 'GPS' in data[0:80]: 
                print(" GPS")
                header_gps(data)
                  
            elif 'GALILEO' in data[0:80]:
                print(" GALILEO")
                header_galileo(data)
                  
            elif 'GLONASS' in data[0:80]:
                header_glonass(data)
                print("glonass")
            
            elif 'BEIDOU' in data[0:80]:
                print("BEIDOU")
                header_beidou(data)
                  
                 #Rinex_3
        else:
            print("Version is not defined")
filepath='/home/ibaad/Downloads/rinexfile/ABMF00GLP_R_20180010000_01H_EN.rnx'
header(filepath)

You may have to close the file at the end

filename.close()

You may have to close the file at the end

filename.close()

No, he does not - with operator guarantees closing of the file

[buran]

can you share the file ABMF00GLP_R_20180010000_01H_EN.rnx you work with?

[ibaad1406]

can't attach the requested due to forum rule. however if you can provide me with your email, i can send it over there.

[buran]

Per forum rules you need to have 5 post in order to be able to attach files. However I've elevated your permissions, so now you can attach file

[volcano63]

This piece of code makes no sense

        while i>=0:
            if data[i]==' ':
                i=i+1
                continue
            else:
                break

1. You are incrementing i- it cannot become lesser than 0, no overflow in Python
   
2. continue is absolutely redundant
   
3. You can run out of data
   

The last - but not the least - it is un-Pythonic, iterating over indices in Python is redundant and considered a bad style.

for char in data:
    if char !+ = ' ':
        break

No need for index at all!

"The type of file that you attached is not allowed. Please remove the attachment or choose a different type"

[buran]

[ibaad1406]

@volcano63
having unpythonic is not the issue. the issue is how to invoke some function inside if else statement.
kindly help me out.
