Conditional Statements
If else
This statement checks the condition present in the if and in case it is true, the operations under if will be executed but in case the condition is false then the operations under else will be executed.
Syntax: if condition:
statements
else:
statements
In case you have more than 2 cases to check, you can use elif to check another condition.
Syntax: if condition 1:
statements
elif condition 2:
statements
else:
statements
Loops
While Loop
This loop is used to perform repetitive tasks until a condition is met. For example printing numbers from 1 to 100 etc.
Syntax: i = 1
while i<101: #condition
print(i) #statements
i = i+1 #Similar as i+=1
For Loop
This loop can be used to iterate over a list, string or a certain range. There is no fixed syntax it depends on the purpose of the loop.
Examples: #For printing numbers in a specific range
for i in range(0,5): #range is from 0-5
print(i) #prints 0,1,2,3,4
word = "Hello"
#For printing the characters present in a string variable
for words in word:
print(words)
'''Output: H
e
l
l
o'''
Nested Loops
Nested loops refer to a loop being inside another loop, that is a loop being "nested" inside another loop.
Example:
while condition:
while condition:
statements
Loop Control Statements
Break: This statement is used to exit from the loop
Continue: It is used to skip the current iteration of the loop.
Pass: Used as a null statement and also acts as a placeholder for future codes.
