More than one statements in a block of uniform indent form a compound statement. Normally each statement is written on separate physical line in editor. However, statements in a block can be written in one line if they are separated by semicolon. Following is code of three statements written in separate lines
a=10 b=20 c=a*b print (c)
These statements can very well be written in one line by putting semicolon in between.
a=10; b=20; c=1*b; print (c)
A new block of increased indent generally starts after : symbol as in case of if, else, while, for, try statements. However, using above syntax, statements in block can be written in one line by putting semicolon. Following is a straight forward example of a block of statements in a for loop
for i in range(5):
print ("Hello")
print ("i=",i)This block can also be written in single line as follows −
for i in range(5): print ("Hello"); print ("i=",i)However, this practice is not allowed if there is a nested block of statements.
