Loops

for and while loops:

for letter in 'Python':
    print(letter, end='-')
print() # end of 1st example

list_data = ['P','y','t','h','o','n']
for d in list_data:
    print(d, end='*')
print() # end of 2nd example

for index in range(len(list_data)):
    print(list_data[index], end='_')
print() # end of 3rd example

count, string = 0, 'Python'
while count <= 5:
    print(string[count], end=' ')
    count+=1
print() # end of 4th example

dict_data = {0:'P', 1:'y', 2:'t', 3:'h', 4:'o', 5:'n'}
for key, value in dict_data.items():
    print(key, value, end=' | ')

Output:

P-y-t-h-o-n-
P*y*t*h*o*n*
P_y_t_h_o_n_
P y t h o n
0 P | 1 y | 2 t | 3 h | 4 o | 5 n |

Loops control statements in Python are:

break: Terminates the loop statement and transfers execution to the statement immediately following the loop.
continue: Causes the loop to skip the remainder of its body and immediately retest it’s condition prior to reiterating.
pass: Used when a statement is required syntactically but you do not want any command or code to execute.

Example:

for letter in 'Python':
    if letter == 'o':
        break
    if letter == 't':
        continue
    if letter == 'P':
        pass
    else:
        print(letter)

Output:

y
n
