Python Program To Check String Has Capital Letter

“How TO Check String Has Capital Letter Using Python” is used to check uppercase letters available or not in a particular string. Here we are going to cover a number of methods to check capital latter in strings using a python program.

01. Example

Using isupper() function with For loop.

  1. Initialize String.
  2. Set a falg value False.
  3. Check with isupper() function.
# String initializing
string = 'Zeroones'

# printing original string
print("The input string : " + str(string))

flag = False
for element in string:
  # checking for capital letter and Decide Flag Value
  if element.isupper():
    flag = True
    break
    
# printing output
print("String Contain Capital Letter: " + str(flag))

Output:

The input string : Zeroones
String Contain Capital Letter: True

 

02. Example

Using isupper() and any() functions.

  1. Initialize String.
  2. Check isupper() with any() function.
  3. Print Result.
# initializing string
string = 'Zeroones'

# printing original string
print("The input string : " + str(string))

# Using any() and isupper() function
flag = any(element.isupper() for element in string)

# printing result
print("String Contain Capital Letter: " + str(flag))

Output:

The input string : Zeroones
String Contain Capital Letter: True

 

03. Example

Using Letters String() and Foor Loop.

  1. Initialize String.
  2. Set Flag value.
  3. Use for loop to decide flag value.
  4. Print Result.
# initializing string
string = 'Zeroones'
letters="ABCDEFGHIJKLMNOPQRSTUVWXYZ"

# printing original string
print("The input string : " + str(string))

flag = False
for element in string:
  if(element in letters):
    flag = True
    break

# print result
print("String Contain Capital Letter: " + str(flag))

Output:

The input string : Zeroones
String Contain Capital Letter: True
