AttributeError: 'str' object has no attribute 'readline' While Reading from File

I run this code:

file=open(filename, 'r')

line=filename.readline()
totallines=0
total=0
while line != "":
    amount=float(line)
    print(format(amount, '.2f'))
    line=filename.readline()
    totallines+=1
    total+=amount
avg=total/totallines
print("The average of the numbers is", format(avg, '.2f'))

and it gives me this error AttributeError: 'str' object has no attribute 'read'

I dont understand what Im doing wrong?

You are calling filename which is a string instead of file in here 

file=open(filename, 'r')
line=filename.readline()

Should be line=file.readline()

In order to improve the code I suggest you use with and as which is faster in execution as well besides being more readable:

with open(filename, 'r') as file
line=file.readline()
