+
+# ### Task 2.1
+# Write a Python program to calculate the length of a string without using the `len` function.
+count = 0
+for i in 'stroka\\n':
+    count += 1
+
+# ### Task 2.2
+# Write a Python program to count the number of characters (character frequency) in a string (ignore case of letters).
+# Examples:
+# ```
+# Input: 'Oh, it is python' 
+# Output: {',': 1, ' ': 3, 'o': 2, 'h': 2, 'i': 2, 't': 2, 's': 1, 'p': 1, 'y': 1, 'n': 1}
+strng = 'Oh, it is python'
+result = {}
+for smbl in strng:
+    result[smbl] = strng.count(smbl)
+print(result)
+
+# ```
+
+# ### Task 2.3
+# Write a Python program that accepts a comma separated sequence of words as input and prints the unique words in sorted form.
+# Examples:
+# ```
+# Input: ['red', 'white', 'black', 'red', 'green', 'black']
+# Output: ['black', 'green', 'red', 'white', 'red']
+# ```
+lst = ['red', 'white', 'black', 'red', 'green', 'black']
+print(sorted(list(set(lst))))
+
+# ### Task 2.3
+# Create a program that asks the user for a number and then prints out a list of all the [divisors](https://en.wikipedia.org/wiki/Divisor) of that number.
+# Examples:
+# ```
+# Input: 60
+# Output: {1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60}
+# ```
+dig = 60
+result = []
+for nmbr in range(1, dig+1):
+    if dig%nmbr == 0:
+        result.append(nmbr)
+print(result)   
+
+# ### Task 2.4
+# Write a Python program to sort a dictionary by key.
+dic = {2: 1, 3: 1, 1: 2} 
+dict(sorted(dic.items()))
+
+# ### Task 2.5
+# Write a Python program to print all unique values of all dictionaries in a list.
+# Examples:
+# ```
+# Input: [{"V":"S001"}, {"V": "S002"}, {"VI": "S001"}, {"VI": "S005"}, {"VII":"S005"}, {"V":"S009"},{"VIII":"S007"}]
+# Output: {'S005', 'S002', 'S007', 'S001', 'S009'}
+# ```
+list_ = [{"V":"S001"}, {"V": "S002"}, {"VI": "S001"}, {"VI": "S005"}, {"VII":"S005"}, {"V":"S009"},{"VIII":"S007"}]
+result = set()
+for _ in list_:
+    result.add(list(_.values())[0])
+    
+print(result)
+
+# ### Task 2.6
+# Write a Python program to convert a given tuple of positive integers into an integer. 
+# Examples:
+# ```
+# Input: (1, 2, 3, 4)
+# Output: 1234
+# ```
+tpl = (1, 2, 3, 4)
+result = ''
+for _ in tpl:
+   result += str(_)
+   
+int(result)
+
+
+# ### Task 2.7
+# Write a program which makes a pretty print of a part of the multiplication table.
+# Examples:
+# ```
+# Input:
+# a = 2
+# b = 4
+# c = 3
+# d = 7
+
+# Output:
+# 	3	4	5	6	7	
+# 2	6	8	10	12	14	
+# 3	9	12	15	18	21	
+# 4	12	16	20	24	28
+# ```
+a = 2
+b = 4
+c = 3
+d = 7
+for i in range(a - 1, b + 1):
+    for j in range(c - 1, d +1):
+        if i == a - 1 and j == c - 1:
+            print(' ', end='\t')
+        elif i == a - 1:
+            print(j, end='\t')
+        elif j == c - 1:
+            print(i, end='\t')
+        else:
+            print(i * j, end='\t')
+    print()
