Getting user input
Write a small script that can calculate the age of a person. The program asks the user to enter birth year and the current year.
Enter your birth year: 1950 Enter the current year: 2020 You are 70 years old.Write a small script that can calculate the weight of an object on Earth. The program asks user to enter mass and calculate the weight.
Enter your weight: 100 Your weight is 98.1 N.
Strings
- Concatenate the string 'Python', 'For','Everyone' to a single string, 'Python for Everyone' - Concatenate the string 'Coding', 'For', 'All' to a single string, 'Coding For All' - Declare a variable name company and assign it to an initial value "Coding For All". - Print company using print() - Print the length of the company string using len() method and print() - Change all the string to capital letters using upper() method - Change all the string to lowercase letters using lower() method - Use capitalize(),title(), swapcase() methods to format the value stored in the variable name company - Slice out the first word of the company string - Check if the string contains a word Coding using the method index or other methods. - Replace the word coding in the string 'Coding For All' to Python using replace or other methods. - Change Python for Everyone to Python for All using the replace method or other methods - Split the string 'Coding For All' at the space using split() method - "Facebook, Google, Microsoft, Apple, IBM, Oracle, Amazon" split the string at the comma - What is character at index 10 in "Coding For All" - Create an acronym or an abbreviation for the name 'Python For Everyone' - Create an acronym or an abbreviation for the name 'Coding For All' - Use index to determine the position of the first occurrence of C in Coding For All - Use index to determine the position of the first occurrence of F in Coding For All - Use rfind to determine the position of the last occurrence of l in Coding For All People. - Use index or find to find the position of the first occurrence of the word because in the following sentence:'You cannot end a sentence with because because because is a conjunction' - Use rindex to find the position of the last occurrence of the word because in the following sentence:'You cannot end a sentence with because because because is a conjunction' - Slice out the phase because because because in the following sentence:'You cannot end a sentence with because because because is a conjunction' - Use search to find the position of the first occurrence of the word because in the following sentence:'You cannot end a sentence with because because because is a conjunction' - Slice out the phase because because because in the following sentence:'You cannot end a sentence with because because because is a conjunction' - Use trim() to remove if there is trailing whitespace at the beginning and the end of a string.E.g " Coding For All ". - Use startswith() method with the string Coding For All make the result true - Use endswith() method with the string Python for Everyone make the result true
Conditionals
- Get user input using input(“Enter your age:”). If the user is 18 or older, give feedback: You are old enough to drive but if not 18 give feedback to wait for the years he supposed to wait for.
```sh
Enter your age: 30
You are old enough to drive.
Enter your age:15
You are left with 3 years to drive.
```
- Compare the values of myAge and yourAge using if … else. Based on the comparison log to console who is older (me or you). Use prompt(“Enter your age:”) to get the age as input.
Enter your age: 30
You are 5 years older than me.
- If a is greater than b return a is greater than b else a is less than b. Output: sh let a = 4; let b = 3; 4 is greater than 3
Write a code which give grade students according to theirs scores:
80-100, A
70-89, B
60-69, C
50-59, D
0 -49, F
- Check if the season is Autumn, Winter, Spring, or Summer. If the user input is:
September, October or November, the season is Autumn.
December, January or February, the season is Winter.
March, April or May, the season is Spring
June, July or August, the season is Summer
