In this article, we will learn how to convert the string to uppercase to python. There are many ways to convert the string to uppercase in Python. We are converting a string to uppercase by using some methods such as python built-in function - upper() function, by using ASCII value, By Using Loops, etc.
Here are some examples of converting a string to uppercase in python.
In this example, we will use the Python built-in function - upper() to convert the string to lowercase.
# Convert String to Uppercase using upper() Function
# Take The Input from User
string = input("Enter The String: ")
string1 = string.upper()
print("\nOriginal String in Lowercase = ", string)
print("The Given String in Uppercase = ", string1)
Enter The String: Tutorials Rack is an online learning website
Original String in Lowercase = Tutorials Rack is an online learning website
The Given String in Uppercase = TUTORIALS RACK IS AN ONLINE LEARNING WEBSITE
In this example, we will use for loop and chr() and ord() function to convert the string to uppercase.
Example 2: Convert String to Uppercase Using For Loop
# Convert String to Uppercase Using For Loop
# Take the Input From the User
string = input("Enter The String: ")
string1 = ''
for i in range(len(string)):
if(string[i] >= 'a' and string[i] <= 'z'):
string1 = string1 + chr((ord(string[i]) - 32))
else:
string1 = string1 + string[i]
print("\nOriginal String in Lowercase = ", string)
print("The Given String in Uppercase = ", string1)
Enter The String: Tutorials Rack is an online learning website
Original String in Lowercase = Tutorials Rack is an online learning website
The Given String in Uppercase = TUTORIALS RACK IS AN ONLINE LEARNING WEBSITE
In this example, we will use while loop, chr() and ord() function to convert the string to uppercase.
Example 3: Convert String to Uppercase Using While Loop
# Convert String to Uppercase Using While Loop
# Take the Input from User
string = input("Enter The String: ")
string1 = ''
i = 0
while(i < len(string)):
if(string[i] >= 'a' and string[i] <= 'z'):
string1 = string1 + chr((ord(string[i]) - 32))
else:
string1 = string1 + string[i]
i = i + 1
print("\nOriginal String in Lowercase = ", string)
print("The Given String in Uppercase = ", string1)
Enter The String: Tutorials Rack is an online learning website
Original String in Lowercase = Tutorials Rack is an online learning website
The Given String in Uppercase = TUTORIALS RACK IS AN ONLINE LEARNING WEBSITE
In this example, we will use ASCII values and chr() and ord() functions to convert the string to uppercase
Example 4: Convert String to Uppercase using ASCII Values
# Convert String to Uppercase using ASCII Values
# Take the Input from the User
string = input("Enter The String: ")
string1 = ''
for i in string:
if(ord(i) >= 97 and ord(i) <= 122):
string1 = string1 + chr((ord(i) - 32))
else:
string1 = string1 + i
print("\nOriginal String in Lowercase = ", string)
print("The Given String in Uppercase = ", string1)
Enter The String: Tutorials Rack is an online learning website
Original String in Lowercase = Tutorials Rack is an online learning website
The Given String in Uppercase = TUTORIALS RACK IS AN ONLINE LEARNING WEBSITE
Example 5: Convert Lowercase String to Uppercase
# Convert Lowercase String to Uppercase
string = input("Enter The String: ")
string1 = ''
for i in string:
if(i >= 'a' and i <= 'z'):
string1 = string1 + chr((ord(i) - 32))
else:
string1 = string1 + i
print("\nOriginal String in Lowercase = ", string)
print("The Given String in Uppercase = ", string1)
Enter The String: Tutorials Rack is an online learning website
Original String in Lowercase = Tutorials Rack is an online learning website
The Given String in Uppercase = TUTORIALS RACK IS AN ONLINE LEARNING WEBSITE
