Learn to design, develop, and execute basic programs in Python.

Zero to Hero in Python for Data Science

This module provides a comprehensive introduction to the tools that help create various programs, such as documents, movies, and games. We'll start with a brief introduction to data science, followed by simple math, real-world problem solving, and precise writing solutions. Next, we'll learn decision-based solutions demonstrated via flowcharts and explained with execution sheets. Finally, we'll learn to translate our solutions into Python programs using variables, conditional statements, loops, strings, lists, and built-in functions. We'll also learn to create our custom functions in Python. After completing this module, we will have acquired the skills to write basic programs in Python.

Understanding Data Science with a focus on Python

What is the result when the following program is executed?

```python
def getSum(y,z):
   mysum = y + z
   return mysum
 
getSum(5,6)
```


What is the result when the following program is executed?
<pre><code class="language-python">def getSum(y,z):
 mysum = y + z
 return mysum
 
getSum(5,6)
</code></pre>

What is the result when the following program is executed?

```python
def run():
 print("run", end=' ')
 
def fun():
 print("fun", end=' ')
 
fun()
print('nothing', end=' ')
run()
```

What is the result when the following program is executed?
<pre><code class="language-python">def run():
 print(&quot;run&quot;, end=' ')
 
def fun():
 print(&quot;fun&quot;, end=' ')
 
fun()
print('nothing', end=' ')
run()
</code></pre>

What is the result when the following program is executed?

```python
for v in reversed(divmod(13 , 4)):
   print(v, end=' ')
```


What is the result when the following program is executed?
<pre><code class="language-python">for v in reversed(divmod(13 , 4)):
 print(v, end=' ')
</code></pre>

What is the result when the following program is executed?

```python
for s in sorted('aAbB'):
   print(s, end=' ')
```

What is the result when the following program is executed?
<pre><code class="language-python">for s in sorted('aAbB'):
 print(s, end=' ')
</code></pre>

What is the result when the following program is executed?

```Python
msg = 'good at work at night'
print(msg.count('at'),msg[msg.find('at'):msg.rfind('at')],end='')
```


What is the result when the following program is executed?
<pre><code class="language-Python">msg = 'good at work at night'
print(msg.count('at'),msg[msg.find('at'):msg.rfind('at')],end='')
</code></pre>

**(Select all that apply.)** Which of the following is true?




(Select all that apply.) Which of the following is true?

`[1, 2, 3, 4, 5, 4, 5] . [1, 2, 3, 4, 5, 4, 5]`


`[1, 2, 3, [4, 5], 4, 5] . [1, 2, 3, [4, 5], 4, 5]`

What is the result when the following program is executed?

```Python
list1 = [1,2,3]
list2 = [4,5]
list3 = list1
list4 = list1.copy()
list1.append(list2)
list1.extend(list2)
print(list3,'.',list4)
```
