In Python, while dealing with string manipulations or formatting, a common issue is the unwanted space between a variable and a period. In this tutorial, we will explain how to get rid of this space by using different formatting techniques, making your Python code look cleaner and more professional.
Step 1: Using String Concatenation
One of the simplest ways to remove the unwanted space between a variable and a period is to use string concatenation with the “+” operator. You can directly concatenate the variable with the period to create a single string.
Here is an example to demonstrate this:
1 2 3 |
name = "Alice" age = 30 print("My name is " + name + " and I am " + str(age) + " years old.") |
As you can see, we have directly concatenated the variables with the strings. The output for this code will be:
My name is Alice and I am 30 years old.
Step 2: Using String Formatting
Another approach to get rid of the space between a variable and a period is to use string formatting. Python provides different ways to format strings, and we will discuss two of them here.
Using %-formatting:
With the %-formatting method, we can format strings by using placeholders. In the following example, we will use the “%s” and “%d” placeholders for string and integer, respectively.
1 2 3 |
name = "Alice" age = 30 print("My name is %s and I am %d years old." % (name, age)) |
This code will also produce the desired output without any unwanted space:
My name is Alice and I am 30 years old.
Using str.format():
The str.format()
method is a more modern way of formatting strings in Python. It allows you to specify placeholders using curly braces “{}” and then provide the variables as arguments to the format()
method.
1 2 3 |
name = "Alice" age = 30 print("My name is {} and I am {} years old.".format(name, age)) |
Just like the previous methods, this code will provide the output without any unwanted space:
My name is Alice and I am 30 years old.
Step 3: Using f-strings (Python 3.6+)
In Python 3.6 and later, f-strings (also known as formatted string literals) have been introduced as a more concise and readable way to format strings. To use f-strings, you need to prepend the string with an “f” or “F” and insert the variables directly inside the curly braces “{}”.
1 2 3 |
name = "Alice" age = 30 print(f"My name is {name} and I am {age} years old.") |
The output will be the same as before:
My name is Alice and I am 30 years old.
Full Code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
name = "Alice" age = 30 # Using string concatenation print("My name is " + name + " and I am " + str(age) + " years old.") # Using %-formatting print("My name is %s and I am %d years old." % (name, age)) # Using str.format() print("My name is {} and I am {} years old.".format(name, age)) # Using f-strings (Python 3.6+) print(f"My name is {name} and I am {age} years old.") |
Conclusion
We have explained several methods to get rid of the unwanted space between a variable and a period in Python. By following these techniques, you can maintain a cleaner output in your Python code. Each method has its advantages and use cases, but using modern methods such as f-strings or str.format()
are generally recommended for their readability and ease of use.
