##Introduction
4+
5+
***The exercise text contents of this repository was collected from GitHub account of [zhiwehu](https://github.com/zhiwehu/Python-programming-exercises). I collected it to practice and solve all the listed problems with python. Even after these collected problems are all set up, I will try to add more problems in near future. If you are a very beginner with python then I hope this 100+ exercise will help you a lot to get your hands free with python.***
6+
7+
***One will find the given problems very simple and easy to understand. A beginner can try 3-5 problems a day which will take a little time to solve but definitely will learn a couple of new stuff (no matter how lazy you are :P ). And after regular practice of only a month, one can find himself solved more than 100++ problems which are obviously not a deniable achievement.***
8+
9+
***In this repository, I will be gradually updating the codebase of the given problems with my own solutions. Also, I may try to explain the code and tell my opinion about the problem if needed. Main Authors solutions are in python 2 & my solutions will be in python 3. Every problem is divided into a template format which is discussed below. There is a [discussion](https://github.com/darkprinx/100-plus-Python-programming-exercises-extended/issues/3) section so don't forget to share your opinion, ideas and feel free to discuss anything wrong or mistake***

# Question 1
3+
4+
### **Question:**
5+
6+
> ***Write a program which will find all such numbers which are divisible by 7 but are not a multiple of 5,
7+
between 2000 and 3200 (both included).The numbers obtained should be printed in a comma-separated sequence on a single line.***
8+
9+
--------------------------------------
10+
### Hints:
11+
> ***Consider use range(#begin, #end) method.***
12+
13+
---------------------------------------
14+
15+
**Main author's Solution: Python 2**
16+
```python
17+
l=[]
18+
for i in range(2000, 3201):
19+
if (i%7==0) and (i%5!=0):
20+
l.append(str(i))
21+
22+
print ','.join(l)
23+
```
24+
----------------------------------------
25+
26+
**My Solution: Python 3**
27+
28+
* **Using for loops**
29+
```python
30+
for i in range(2000,3201):
31+
if i%7 == 0 and i%5!=0:
32+
print(i,end=',')
33+
print("\b")
34+
```
35+
-------------------------------
36+
37+
* **Using generators and list comprehension**
38+
```python
39+
print(*(i for i in range(2000, 3201) if i%7 == 0 and i%5 != 0), sep=",")
40+
```
41+
42+
# Question 2
43+
44+
### **Question:**
45+
46+
> ***Write a program which can compute the factorial of a given numbers.The results should be printed in a comma-separated sequence on a single line.Suppose the following input is supplied to the program: 8
47+
Then, the output should be:40320***
48+
49+
--------------------
50+
### Hints:
51+
>***In case of input data being supplied to the question, it should be assumed to be a console input.***
52+
53+
---------------
54+
**Main author's Solution: Python 2**
55+
```python
56+
def fact(x):
57+
if x == 0:
58+
return 1
59+
return x * fact(x - 1)
60+
61+
x = int(raw_input())
62+
print fact(x)
63+
```
64+
------------
65+
**My Solution: Python 3**
66+
67+
* **Using While Loop**
68+
```python
69+
n = int(input()) #input() function takes input as string type
70+
#int() converts it to integer type
71+
fact = 1
72+
i = 1
73+
while i <= n:
74+
fact = fact * i;
75+
i = i + 1
76+
print(fact)
77+
```
78+
* **Using For Loop**
79+
```python
80+
n = int(input()) #input() function takes input as string type
81+
#int() converts it to integer type
82+
fact = 1
83+
for i in range(1,n+1):
84+
fact = fact * i
85+
print(fact)
86+
```
87+
* **Using Lambda Function**
88+
```python
89+
# Solution by: harshraj22
90+
91+
n = int(input())
92+
def shortFact(x): return 1 if x <= 1 else x*shortFact(x-1)
93+
print(shortFact(n))
94+
95+
```
96+
-------------------
97+
98+
# Question 3
99+
100+
### **Question:**
101+
102+
>***With a given integral number n, write a program to generate a dictionary that contains (i, i x i) such that is an integral number between 1 and n (both included). and then the program should print the dictionary.Suppose the following input is supplied to the program: 8***
103+
104+
>***Then, the output should be:***
105+
```
106+
{1: 1, 2: 4, 3: 9, 4: 16, 5: 25, 6: 36, 7: 49, 8: 64}
107+
```
108+
------------------
109+
110+
### Hints:
111+
>***In case of input data being supplied to the question, it should be assumed to be a console input.Consider use dict()***
112+
113+
-----------------
114+
115+
**Main author's Solution: Python 2**
116+
```python
117+
n = int(raw_input())
118+
d = dict()
119+
for i in range(1,n+1):
120+
d[i] = i * i
121+
print d
122+
```
123+
124+
**My Solution: Python 3:**
125+
```python
126+
n = int(input())
127+
ans = {}
128+
for i in range (1,n+1):
129+
ans[i] = i * i
130+
print(ans)
131+
```
132+
**OR**
133+
```python
134+
# This is done with dictionary comprehension method
135+
n = int(input())
136+
ans={i : i*i for i in range(1,n+1)}
137+
print(ans)
138+
```
139+
----------------------------------
140+
141+
## Conclusion
142+
***These was the solved problems of day 1. The above problems are very easy for the basic syntex learners.I have shown some easy ways of coding in my solutions. Lets see how to face and attack new problems in the next day.***
