File reading: Character By Character

Question: 1
Python program to read the contents of a file character by character and display them?(Method:1)
Sol:

def file_read():
     f=open("abc.txt")
     while True:
         c=f.read(1)
         if not c:
             #print("end of file")
             break
         print(c,end='')

#function calling
file_read()

Question: 2
Python program to read the contents of a file character by character and display them?(Method : 2)
Sol:

def file_read1():
     with open("abc.txt") as f:
         while True:
             c=f.read(1)
             if not c:
                 #print("end of file")
                 break
             print(c,end='')
#function calling
file_read1()

Question: 3
Python program to read the contents of the file “abc.txt” and print its length.
Sol:

def count_len():
     le=0
     with open("abc.txt") as f:
         while True:
             c=f.read(1)
             if not c:
                 break
             print(c,end='')
             le=le+1
         print("length of file ",le)
 #function calling
 count_len()

Question : 4
Python program to read the contents of the file “story.txt”. Further count and print total lower case alphabets in the file
Sol:

def count_lower():
     lo=0
     with open("story.txt") as f:
         while True:
             c=f.read(1)
             if not c:
                 break
             print(c,end='')
             if(c>='a' and c<='z'):
                 lo=lo+1
         print("total lower case alphabets ",lo)
 function calling
 count_lower()

Question: 5
Python program to read the contents of the file “story.txt”. Further, count and print total upper case alphabets in the file.
Sol:

def count_upper():
     u=0
     with open("story.txt") as f:
         while True:
             c=f.read(1)
             if not c:
                 break
             print(c,end='')
             if(c>='A' and c<='Z'):
                 u=u+1
         print("total upper case alphabets ",u)
 function calling
 count_upper()
