# W3Resources (Basic Python Part - I)

### 1. Write a Python program to print the following string in a specific format (see the output).

### Sample String : "Twinkle, twinkle, little star, How I wonder what you are! Up above the world so high, Like a diamond in the sky. Twinkle, twinkle, little star, How I wonder what you are"



### Output :

```

Twinkle, twinkle, little star,

	How I wonder what you are! 

		Up above the world so high,   		

		Like a diamond in the sky. 

Twinkle, twinkle, little star, 

	How I wonder what you are

```

### Code

```

print("Twinkle, twinkle, little star,")

print("	       How I wonder what you are! ")

print("		         Up above the world so high,")

print("		         Like a diamond in the sky.")

print("Twinkle, twinkle, little star,")

print(" 	   How I wonder what you are")

```



### 2. Write a Python program to find out what version of Python you are using.

### Code



```

import sys

print("Python Version: ", sys.version)

```



### 3. Write a Python program to display the current date and time.

### Sample Output :

```

Current date and time :

2014-07-05 14:34:14

```

### Code

```

import datetime

print("Current Date and Time: ", datetime.datetime.now())

```



### 4. Write a Python program that calculates the area of a circle based on the radius entered by the user.

```

Sample Output :

r = 1.1

Area = 3.8013271108436504

```

### Code

```

print("Area of Circle Program!!")

radius = float(input("Input Radius: "))

area_of_circle = (22/7) * radius ** 2

print("Area of Circle = ", area_of_circle)

```



### 5. Write a Python program that accepts the user's first and last name and prints them in reverse order with a space between them.

### Code

```

first_name = input("Input First Name: ")

last_name = input("Input last name: ")

print(last_name, first_name)

```



### 6. Write a Python program that accepts a sequence of comma-separated numbers from the user and generates a list and a tuple of those numbers.

## Sample data : 3, 5, 7, 23

```

Output :

List : ['3', ' 5', ' 7', ' 23']

Tuple : ('3', ' 5', ' 7', ' 23')

```

### Code

```

values = input("Input some values followed by commans: ")

list_value = values.split(",")

print(List: list_value)

print(Tuple: tuple(list_value))

```



### 7. Write a Python program that accepts a filename from the user and prints the extension of the file.

### Sample filename : abc.java

```

Output : java

```

### Code

```

file_name = input("Enter file name with its extension: ")

ext_split = file_name.split(".")

print("File Extension is:", ext_split[-1])

```



### 8. Write a Python program to display the first and last colors from the following list.

### Sample data: color_list = ["Red","Green","White" ,"Black"]

### Code

```

color_list = ["Red", "Green", "White", "Black"]

print(color_list[0], color_list[-1])

```



### 9. Write a Python program to display the examination schedule. (extract the date from exam_st_date).

### Sample Input: exam_st_date = (11, 12, 2014)

```

Sample Output : The examination will start from : 11 / 12 / 2014

```

### Code

```

exam_st_date = (11, 12, 2014)

print("The examination will start from: ", exam_st_date[0], "/", exam_st_date[1], "/", exam_st_date[2])

```



### 10. Write a Python program that accepts an integer (n) and computes the value of n+nn+nnn.

### Sample value of n is 5

### Expected Result : 615

### Code

```

n = int(input("Enter n value: "))

n1 = int("%s" % n)

n2 = int("%s%s" % (n, n))

n3 = int("%s%s%s" % (n, n, n))

print(n1 + n2 + n3)

```



### 11. Write a Python program to print the documents (syntax, description etc.) of Python built-in function(s).

### Sample function : abs()

```

Expected Result :

abs(number) -> number

Return the absolute value of the argument.

```



### 12. Write a Python program that prints the calendar for a given month and year.

#### Note : Use 'calendar' module.

### Code

```chatinput

import calendar



month = int(input("Enter month: "))

year = int(input("Enter Year: "))

cal = calendar.month(year, month)

print(cal)

```



### 13. Write a Python program to print the following 'here document'.

### Sample string : 

```

a string that you "don't" have to escape

This

is a ....... multi-line

heredoc string --------> example

```



### 14. Write a Python program to calculate the number of days between two dates.

### Sample dates : (2014, 7, 2), (2014, 7, 11)

### Expected output : 9 days

### Code

```chatinput

from datetime import date



date1 = date(2014, 7, 29)

date2 = date(2014, 8, 3)

print("Remaining days: ", abs(date1 - date2))



```
