How to get list using for loop in python and we have to capitalize the first letter of the every element?

You are given a list of string elements and asked to return a list which contains each element of the string in title case or in other words first character of the string would be in upper case and remaining all characters in lower case

Sample Input:

['VARMA', 'raj', 'Gupta', 'SaNdeeP']

Sample Output

['Varma', 'Raj', 'Gupta', 'Sandeep']

Below code is working fine !

input_list = ['VARMA', 'raj', 'Gupta', 'SaNdeeP']
output=[] 
for i in range(len(input_list)): # length of input 
    output.append(input_list[i][0].upper() + input_list[i][1:].lower()) # first character as uppercase and remaining characters a lower case
print(output)

Output

['Varma', 'Raj', 'Gupta', 'Sandeep']

You can you capitalize() method of string and list comprehension as followings:

data = [ ' Verma' ,  ' raj ' ,  ' Gupta ' ,  ' SaNdeeP ' ]
capitalized = [ a.capitalize( )  for a in data ]
print ( capitalized )

lt = ['VARMA', 'raj', 'Gupta', 'SaNdeeP']

Using Map Function 

print(list(map(lambda x : x.title(),lt)))
Output - ['Varma', 'Raj', 'Gupta', 'Sandeep']

Using str.title()

a = ['VARMA', 'raj', 'Gupta', 'SaNdeeP']
res = [x.title() for x in a]
print(res)
#['Varma', 'Raj', 'Gupta', 'Sandeep']

The answer by @Harun is probably the best one here, but as an alternative, and a more general answer, we can consider using re.sub with a callback function:

data = ['VARMA', 'raj', 'Gupta', 'SaNdeeP']
capitalized = [re.sub(r'^(.)(.*)$', lambda m: m.group(1).upper() + m.group(2).lower(), a)
    for a in data]
print(capitalized)

This prints:

['Varma', 'Raj', 'Gupta', 'Sandeep']
